These modules operate over a wide range of input voltage (VIN = 3Vdc - 14.4Vdc) and provide a precisely regulated output voltage from 0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current and over temperature protection in the controller. The module also includes the Tunable LoopTM feature that 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. * UL is a registered trademark of Underwriters Laboratories, Inc.

Input ripple voltage for various output voltages with 1x22 F or 2x22 F ceramic capacitors at the input (6A load). Input voltage is 12V. Scope Bandwidth at 20MHz Output Filtering These modules are designed for low output ripple voltage and will meet the maximum output ripple specification with suggested 2x0.047F+1x1uF ceramic decoupling capacitors and 1x47 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. For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950-1 2nd, CSA C22.2 No. 60950-1-07, DIN EN 609501:2006 + A11 (VDE0805 Teil 1 + A11):2009-11; EN 609501:2006 + A11:2009-03. 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 with a fast acting fuse (e.g. ABC Bussmann) with a maximum rating of 20 A in the positive input lead. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 38 provides output ripple information, measured with a scope with its Bandwidth limited to 20MHz for different external capacitance values at various Vo and a full load current of 6A. 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. June 24, 2014 (c)2014 General Electric Corporation. All rights reserved. Page 12 GE Data Sheet 6A Analog SlimLynxTM Encapsulated: Non-Isolated DC-DC Power Modules 3Vdc -14.4Vdc input; 0.6Vdc to 5.5Vdc output; 6A Output Current SlimLynxTM The 6A Analog Encapsulated power modules feature an On/Off pin for remote On/Off operation. 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 should be always referenced to ground. For either On/Off logic option, leaving the On/Off pin disconnected will turn the module ON when input voltage is present. For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 39. When the external transistor Q2 is in the OFF state, the internal transistor Q7 is turned ON, which turn Q3 OFF which keeps Q6 OFF and Q5 OFF. This allows the internal PWM #Enable signal to be pulled up by the internal 3.3V, thus turning the module ON. When transistor Q2 is turned ON, the On/Off pin is pulled low, which turns Q7 OFF which turns Q3, Q6 and Q5 ON and the internal PWM #Enable signal is pulled low and the module is OFF. A suggested value for Rpullup is 20k. For negative logic On/Off modules, the circuit configuration is shown in Fig. 40. The On/Off pin should be pulled high with an external pull-up resistor (suggested value for the 3V to 14V input range is 20Kohms). When transistor Q2 is in the OFF state, the On/Off pin is pulled high, transistor Q3 is turned ON. This turns Q6 ON, followed by Q5 turning ON which pulls the internal ENABLE low and the module is OFF. To turn the module ON, Q2 is turned ON pulling the On/Off pin low, turning transistor Q3 OFF, which keeps Q6 and Q5 OFF resulting in the PWM Enable pin going high. The module has monotonic start-up and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. Startup into Pre-biased Output The module can start into a prebiased output as long as the prebias voltage is 0.5V less than the set output voltage. Analog Output Voltage Programming The output voltage of the module is programmable to any voltage from 0.6dc to 5.5Vdc by connecting a resistor between the Trim and SIG_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. 41. The Upper Limit curve shows that for output voltages lower than 1V, the input voltage must be lower than the maximum of 14.4V. The Lower Limit curve shows that for output voltages higher than 0.6V, the input voltage needs to be larger than the minimum of 3V. 16 14 Input Voltage (v) Remote On/Off 12 Upper 10 8 6 4 Lower 2 0 0.5 3.3V SlimLynx Module +VIN VIN 100pF 20K ON/OFF 20K Q7 + Q2 _ 100K 20K 2K 20K 20K V ON/OFF Q3 20K 2 2.5 3 3.5 4 4.5 5 5.5 6 Output Voltage (V) Figure 41.

This is accomplished via an additional sequencing pin. When not using the sequencing feature, leave it unconnected. The voltage applied to the SEQ pin should be scaled down by the same ratio as used to scale the output voltage down to the reference voltage of the module. This is accomplished by an external resistive divider connected across the sequencing voltage before it is fed to the SEQ pin as shown in Fig. 44. In addition, a small capacitor (suggested value 100pF) should be connected across the lower resistor R1. Remote Sense The power module has a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage between the sense pins (VS+ and VS-). The voltage drop between the sense pins and the VOUT and GND pins of the module should not exceed 0.5V. For all SlimLynx modules, the minimum recommended delay between the ON/OFF signal and the sequencing signal is 10ms to ensure that the module output is ramped up according to the sequencing signal. This ensures that the module soft-start routine is completed before the sequencing signal is allowed to ramp up. Voltage Margining Output voltage margining can be implemented in the module by connecting a resistor, Rmargin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to output pin for margining-down. Figure 43 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at http://www.geindustrial.com/products/embedded-power, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin.

Page 14 GE Data Sheet 6A Analog SlimLynxTM Encapsulated: Non-Isolated DC-DC Power Modules 3Vdc -14.4Vdc input; 0.6Vdc to 5.5Vdc output; 6A Output Current sequencing voltage must be set higher than the set-point voltage of the module. The output voltage follows the sequencing voltage on a one-to-one basis. By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. The module's output can track the SEQ pin signal with slopes of up to 0.5V/msec during power-up or power-down. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their setpoint voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential. 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. Tunable LoopTM The module has a feature that optimizes transient response of the module called Tunable LoopTM. External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Figure 38) 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. 46. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. Overtemperature Protection To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shut down if the overtemperature threshold of 150oC(typ) is exceeded at the thermal reference point Tref .Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. VOUT VS+ RTune MODULE TRIM Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Synchronization The module switching frequency can be synchronized to a signal with an external frequency within a specified range. Synchronization can be done by using the external signal applied to the SYNC pin of the module as shown in Fig. 45, with the converter being synchronized by the rising edge of the external signal. The Electrical Specifications table specifies the requirements of the external SYNC signal. If the SYNC pin is not used, the module should free run at the default switching frequency. If synchronization is not being used, connect the SYNC pin to GND. MODULE SYNC + GND Figure 45. External source connections to synchronize switching frequency of the module. June 24, 2014 CO CTune RTrim SIG_GND GND Figure. 46. Circuit diagram showing connection of RTUME and CTUNE to tune the control loop of the module. Recommended values of RTUNE and CTUNE for different output capacitor combinations are given in Table 2. Table 2 shows the recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 1000uF that might be needed for an application to meet output ripple and noise requirements. Selecting RTUNE and CTUNE according to Table 2 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 3 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 3A to 6A step change (50% of full load), with an input voltage of 12V. Please contact your GE Critical Power technical representative to obtain more details of this feature as well as for guidelines on how to select the right value of external R-C to tune the module for best transient performance and stable operation for other output capacitance values.

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 Encapsulated 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 The encapsulated SlimLynx product can be assembled on the bottom side of a customer board. The surface tension of the solder connections between the customer board and the module are sufficient to hold the module during the top side reflow process. No additional glue or adhesive is required. Lead Free Soldering The 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. 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. For guidance on appropriate soldering, cleaning and drying procedures, refer to Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04-001). Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. D (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. 50. Soldering outside of the recommended profile requires testing to verify results and performance. MSL Rating The 6A Analog SlimLynxTM Encapsulated modules have a MSL rating of 3.
