Licensed ISO** 9001 and ISO 14001 certified manufacturing facilities Vin+ VIN Vout+ VOUT VS+ RTUNE MODULE Cin R Q1 CTUNE ON/OFF Co TRIM RTrim GND Description The 9-36V ProLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 3A of output current. These modules operate over an extra wide range of input voltage (VIN = 9Vdc-36Vdc) and provide a precisely regulated output voltage from 3Vdc to 18Vdc, programmable via an external resistor. Two new features added with this family of products are the ability to externally tune the voltage control loop and a variable current limit inversely dependent on output voltage. Other features include remote On/Off, adjustable output voltage, over current and overtemperature protection. The Tunable LoopTM, allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area and AutoLimit enables the module to deliver the max possible output power across the entire voltage range. * UL is a registered trademark of Underwriters Laboratories, Inc.

A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. COM To minimize input voltage ripple, ceramic capacitors are recommended at the input of the module. Figure 28 shows the input ripple voltage for various output voltages at maximum load current with 2x10 F or 3x10 F ceramic capacitors and an input of 12V while Fig. 29 shows the input ripple for an input voltage of 28V.

Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figures 6 and 7 provides output ripple information for different external capacitance values at various Vo and for full load currents. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. Optimal performance of the module can be achieved by using the Tunable LoopTM feature described later in this data sheet. 50 Ripple(mVp-p) 30 20 10 3 4 5 6 Output Voltage(Volts) 1x10uF 2x10uF 4x10uF 150 130 110 90 70 50 30 10 2 4 6 8 10 12 14 16 18 Output Voltage(Volts) Figure 31 Output ripple voltage for various output voltages with external 1x10 F, 2x10 F or 4x10 F ceramic capacitors at the output (max load).

For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a fast-acting fuse with a maximum rating of 8A in the positive input lead. 1x10uF 2x10uF 4x10uF 40 170 Ripple(mVp-p) The 9-36V ProLynxTM modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 F ceramic and 10 F ceramic capacitors at the output of the module. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. 7 8 Figure 30 Output ripple voltage for various output voltages with external 1x10 F, 2x10 F or 4x10 F ceramic capacitors at the output (max load).

Two On/Off logic options are available. In the Positive Logic On/Off option, (device code suffix "4" - see Ordering Information), the module turns ON during a logic High on the On/Off pin and turns OFF during a logic Low. With the Negative Logic On/Off option, (no device code suffix, see Ordering Information), the module turns OFF during logic High and ON during logic Low. The On/Off signal is always referenced to ground. For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 32. When the external transistor Q1 is in the OFF state, the ON/OFF pin is pulled high and transistor Q2 is OFF leading to Q3 also being OFF which turns the module ON. The external resistor Rpullup (100k recommended) must be sized so that VON/OFF is never more than 12V when Q1 is OFF. In particular, if Vpullup is made the same as the input voltage Vin, the resistor Rpullup must be large enough so that VON/OFF is never more than 12V. If the On/Off pin is left floating the module will be in the ON state. For negative logic On/Off modules, the circuit configuration is shown in Fig. 33. When the external transistor Q1 is in the ON state, the ON/OFF pin is pulled low causing transistor Q2 to be OFF and the module to be turned ON. To turn the module OFF, Q1 is turned OFF, causing the ON/OFF pin to be pulled high turing Q2 ON and the module to be turned OFF. Leaving the On/Off pin floating will leave the module in an OFF state.

Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. The 9-36V ProLynx modules employ an innovative, patent pending, `AutoLimit' capability. This results in automatic scaling of current limit with output voltage through an inverse relationship of the current limit threshold with the output voltage. This feature shown graphically in Fig. 34, allows higher output currents to be drawn from the module at lower output voltages thereby optimizing the power delivery capability of the module. +5V 3.5 Rp ullu p 2 2K ISS Q2 ON /OFF + VON/OFF Q1 PWM Ena ble 2 2K Q3 4 2K 2 2K CSS GN D _ Figure 32.

Over Temperature Protection To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the overtemperature threshold of 130oC is exceeded at the thermal reference point Tref. The thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. June 16, 2020 (c)2015 General Electric Company. All rights reserved.

The module will begin to operate at an input voltage above the under voltage lockout turn-on threshold. Output Voltage Programming The output voltage of the 9-36V ProLynxTM module can be programmed to any voltage from 3Vdc to 18Vdc by connecting a resistor between the Trim and GND pins of the module. Certain restrictions apply on the output voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input Voltage Set Point Area plot in Fig. 9. Without an external resistor between Trim and GND pins, the output of the module will be 0.7Vdc. To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equation: By using a 0.5% tolerance trim resistor with a TC of 100ppm, a set point tolerance of 1.5% can be achieved as specified in the electrical specification. Remote Sense The 9-36V ProLynxTM power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage between the VS+ and Vo pin. The voltage between the VS+ pin and Vo pin will not exceed 0.5V. VIN(+) VO(+) VS+ ON/OFF LOAD TRIM Rtrim 70 Rtrim = k (Vo - 0.7 ) GND Rtrim is the external resistor in k, and Vo is the desired output voltage. Figure 36.

External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Figures 30 and 31) and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes. Adding external capacitance however affects the voltage control loop of the module, typically causing the loop to slow down with sluggish response. Larger values of external capacitance could also cause the module to become unstable. The Tunable LoopTM allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. The Tunable LoopTM is implemented by connecting a series R-C between the VS+ and TRIM pins of the module, as shown in Fig. 38. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. Recommended values of RTUNE and CTUNE for different output capacitor combinations are given in Tables 2, 3 and 4. Tables 2 and 3 show recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 100F that might be needed for an application to meet output ripple and noise requirements. Selecting RTUNE and CTUNE according to Tables 2 and 3 will ensure stable operation of the module In applications with tight output voltage limits in the presence of dynamic current loading, additional output capacitance will be required. Table 4 lists recommended values of RTUNE and CTUNE in order to meet 2% output voltage deviation limits for some common output voltages in the presence of a 50% of full load step change with an input voltage of 12 or 28V.

The ruggedized modules have been successfully tested to the following conditions: Non operating random vibration: Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms (Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes. Operating shock to 40G per Mil Std. 810G, Method 516.4 Procedure I: The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock impulse characteristics as follows: All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes. Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of 40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen shocks. Operating vibration per Mil Std 810G, Method 514.5 Procedure I: The APXW003 modules are designed and tested to vibration levels as outlined in MIL-STD-810G, Method 514.5, and Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 1 and Table 2 for all axes. Full compliance with performance specifications was required during the performance test. No damage was allowed to the module and full compliance to performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and endurance levels shown in Table 5 and Table 6 for all axes. The performance test has been split, with one half accomplished before the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16 minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours minimum per axis.

The modules are fitted with a label designed to provide a large surface area for pick and place operations. The label meets all the requirements for surface mount processing, as well as safety standards, and is able to withstand reflow temperatures of up to 300oC. The label also carries product information such as product code, serial number and the location of manufacture. Nozzle Recommendations The module weight has been kept to a minimum by using open frame construction. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The minimum recommended inside nozzle diameter for reliable operation is 3mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 7 mm. Bottom Side / First Side Assembly This module is not recommended for assembly on the bottom side of a customer board. If such an assembly is attempted, components may fall off the module during the second reflow process. Lead Free Soldering The 9-36V ProLynxTM modules are lead-free (Pb-free) and RoHS compliant and fully compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. C (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package (table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 41. Soldering outside of the recommended profile requires testing to verify results and performance. For questions regarding Land grid array(LGA) soldering, solder volume; please contact GE for special manufacturing process instructions. MSL Rating The 9-36V ProLynxTM modules have a MSL rating of 2a. Storage and Handling The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of 30C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40 C, < 90% relative humidity. 300 Per J-STD-020 Rev.

Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly.

To turn the module OFF, Q2 is turned OFF, which turns Q1 OFF causing the ON/OFF pin to be pulled high turning Q5 ON and the module to be turned OFF. If the On/Off pin is left floating, the module will be in the OFF state. Input Voltage Range The 9-36V ProLynxTM modules when connected in a negative output application will support a maximum input voltage which is also a function of the output voltage. The sum of the applied input voltage and magnitude of the output voltage cannot exceed 36V. Vin(applied) +|Vout| 36 and Vout-3V. For e.g. with a -12V output system the max input voltage that can applied is only 24V. However, Figure 35 showing variation of output voltage with Input Voltage should still be considered for determining the required minimum input voltage. Input voltage turn-on threshold remains the same as the positive output connection. However the input turn-off threshold tracks the output voltage and is reduced by the same level. The listed input Turn-Off threshold of 7.35V when applied to a -3.3Vout application will be measured as a 4.05V (7.35V - 3.3V) threshold. Operating at input voltages below 9V may cause the module to shut down earlier due to OCP inception Figure 44. Schematic Connection of 5A ProLynx module for negative output applications. Output Voltage Range Remote Enable The 9-36V ProLynxTM modules will support the values of trim resistors indicated in Table 1 to generate the same output voltage, except with sign inversion Figures 33 and 34 still apply for remote On/Off operation. However the On/Off threshold is now with respect to -Vout instead of Ground. Before the module turns on, output is zero so GND and -Vout are at the same potential. After the modules turns on, -Vout moves down and so will the ON/OFF threshold. The following level shifting circuit can be used in applications to limit exposure of the negative output voltage to the On/Off circuitry. MODULE Overcurrent Protection The 9-36V ProLynx modules will automatic scale current limit with output voltage through an inverse relationship of the current limit threshold even in negative output voltage mode. This feature is shown graphically in Fig. 34, allows higher output currents to be drawn from the module at lower output voltages thereby optimizing the power delivery capability of the module.
