This is the most "low-voltage" current available from a standard 1" x 2" package, and these power converters exemplify Murata Power Solutions' relentless drive to bring you more power/current, from standard packages, without compromising reliability or resorting to thermal specmanship. By combining a high-frequency, high-efficiency (to 88%), synchronous-rectifier topology with the newest components and time-tested, fully automated, SMT-on-pcb construction, these UWR Models are able to bring you 7-15W (@ up to 6A) in the standard 1" x 2" package from which most competitors can only get 5-10W (@ 3-4A). All UWR's deliver their full output power over ambient temperature ranges from -40C to as high as +70C (model and input voltage dependent) without heat sinks or supplemental forced-air cooling. Devices derate to +100C. Output voltages are 1.2, 1.5, 1.8, 2.5, 3.3, 5, 12 or 15 Volts. Input voltage ranges are 10-18V (D12 models), 18-36V (D24 models) or 36-75V (D48 models). All models feature input pi filters, input undervoltage and overvoltage lockout, input reverse-polarity protection, output overvoltage protection, output current limiting, and continuous short-circuit protection. On/off control and outputtrim functions are optional (see Optional Functions). All models are designed to meet IEC950, UL1950 and EN60950-1, 2nd Edition safety requirements. D48 models (36-75V inputs) are CE marked. UWR 7-15W DC/DC's are packaged in lowcost, light-weight, diallyl phthalate (UL94V-0 rated) plastic packages with standoffs. EMC compliance is achieved via a low-noise design rather than through expensive metal shielding. n Standard 1" x 2" packages and pinouts n Optional VOUT trim and on/off control +VIN (1) +VOUT (4) SWITCH CONTROL COMMON (6) -VIN (2) PWM CONTROLLER ON/OFF CONTROL (3) (OPTIONAL) OPTO ISOLATION REFERENCE & ERROR AMP TRIM (5) (OPTIONAL) UVLO & OVLO COMPARATORS Typical topology is shown.

See Optional Functions or contact MPS for details. The On/Off Control is designed to be driven with open-collector logic or the application of appropriate voltages (referenced to -Input, pin 2). Applying a voltage to the On/Off Control pin when no input voltage is applied to the converter may cause permanent damage. See Technical Notes.

Devices can withstand sustained output short circuits without damage. Case Temperature +100C Storage Temperature -40 to +105C Lead Temperature See soldering guidelines These are stress ratings. Exposure of devices to greater than any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifications Table is not implied. www.murata-ps.com/support MDC_UWR_7-15.I03 Page 3 of 13 UWR Models Single Output, High-Density, 6 Amp/15 Watt DC/DC Converters Floating Outputs Since these are isolated DC/DC converters, their outputs are "floating." Designers will usually use the output Common (pin 6) as the ground/return of the load circuit. You can, however, use the +Output (pin 4) as ground/return to effectively reverse the output polarity. Minimum Output Loading Requirements 1.2 to 5V models employ a synchronous-rectifier design topology. All models regulate within spec and are stable under no-load conditions. 12/15V models employ a traditional forward architecture and require 10% loading (125mA for 12V models, 100mA for 15V models) to achieve their listed regulation specs. 12/15V models also have a minimum-load-for-stability requirement (20mA). For 12/15V models, operation below 20mA or 10% loading will be stable but regulation may degrade. A 100F output capacitor is recommended below 10% loading. Users should verify whether this relaxed regulation will have any effect on output circuits. If so, add a small load of 10% or greater. Operation under no-load conditions will not damage 12/15V converters. However they may not meet all listed specifications. Filtering and Noise Reduction All A-Series UWR DC/DC Converters achieve their rated ripple and noise specifications using the external input and output capacitors specified in the Performance/Functional Specifications table. In critical applications, input/ output noise may be further reduced by installing additional external I/O caps. Input capacitors should be selected for bulk capacitance, low ESR and high rms-ripple-current ratings. Output capacitors should be selected for low ESR and appropriate frequency response. All caps should have appropriate voltage ratings and be mounted 2-3 inches from the converter to achieve published ratings. The most effective combination of external I/O capacitors will be a function of your particular load and layout conditions. Input Fusing Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. For MPS's A-Series UWR 7-15 Watt DC/DC Converters, you should use fast-blow type fuses with values no greater than the following. VIN Range "D12A" Models "D24A" Models "D48A" Models Fuse Value 3 Amps 2 Amps 1 Amp Maximum Case Temperature The +100 degree C. maximum outside case temperature specification is based on much empirical testing on encapsulated units. Those tests show that if the case exterior can be maintained at or below +100C., the hottest internal components' package temperatures will not exceed +128C. because of the internal temperature gradient to the exterior case. This latter +128C. internal figure is a safety margin offering more protection for the internal components. The +100C. case specification must be achieved by the user's combination of lower output current and/or higher airflow. If you attempt any of your own case temperature testing, please be aware of the heatsinking effect of attaching wired thermocouples to surfaces. An infra- red camera is a another alternative which avoids the TC heatsinking effect. But the IR camera must be calibrated frequently and accurately. Remember too that it is quite difficult to accurately measure airflow right at the converter. Murata Power Solutions uses a calibrated wind tunnel with large amounts of data history. Because of thermal time constants, allow plenty of time for temperature stabilization. Trimming Output Voltages These converters have a trim capability (pin 5) that allows users to adjust the output voltage 5%. Adjustments to the output voltage can be accomplished via a trim pot, Figure 2, or a single fixed resistor as shown in Figures 3 and 4. A single fixed resistor can increase or decrease the output voltage depending on its connection. Fixed resistors should have an absolute TCR less than 100ppm/C to minimize sensitivity to changes in temperature. A single resistor connected from the Trim (pin 5) to the +Output (pin 4), see Figure 3, will decrease the output voltage. A resistor connected from the Trim (pin 5) to Output Common (pin 6) will increase the output voltage. Trim adjustment greater than 5% can have an adverse effect on the converter's performance and is not recommended. 1 2 3 +VIN -VIN ON/OFF CONTROL +VOUT TRIM COMMON 4 5 20k 5-22 Turns LOAD 6 Figure 2.

Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown/Lockout limit (34V for "D48A" models). Subsequent re-start will not occur until the input is brought back up to the Start-Up Threshold. This built-in hysteresis obviously avoids any indeterminate on/off situations at a single voltage. Start-Up Time The VIN to VOUT Start-Up Time is the interval between the time at which a ramping input voltage crosses the turn-on threshold point and the fully-loaded output voltage enters and remains within its specified accuracy band. Actual measured times will vary with input source impedance, external input capacitance, and the slew rate and final value of the input voltage as it appears to the converter. The On/Off to VOUT Start-Up Time assumes the converter is turned off via the On/Off Control with the nominal input voltage already applied to the converter. The specification defines the interval between the time at which the converter is turned on and the fully-loaded output voltage enters and remains within its specified accuracy band. Accuracy of adjustment is subject to tolerances or resistor values and factory-adjusted output accuracy. VO = desired output voltage. www.murata-ps.com/support MDC_UWR_7-15.I03 Page 5 of 13 UWR Models Single Output, High-Density, 6 Amp/15 Watt DC/DC Converters Temperature Derating Curves for UWR 7-15W A-Series D12A (10-18V) Temperature Derating D24A and D48A Temperature Derating for 1.5V Output Models 10 9 VIN = 18V-27V (D24A) 7 6 VIN = 18V-30V (D24A) VIN = 36V-60V (D48A) 5 4 VIN = 18V-36V (D24A) 3 15.0 VIN = 36V-75V (D48A) 2 13.5 1 VOUT = 2.5V, 5V, 12V and 15V 12.0 0 -40 10.5 Output Power (Watts) VIN = 36V-48V (D48A) 8 Output Power (Watts) The thermal performance of A-Series UWR 7-15 Watt DC/DC Converters is depicted in the derating curves shown below.

Contact MPS. Optional Functions The A-Series 7-15W DC/DC Converters offer numerous electrical/ mechanical options. Per the Ordering Guide on page 2, the trailing "A" (A-Series) in each part number pertains to the base part number. Part-number suffixes are added after the "A," indicating the selection of standard options. The resulting part number is a "standard product" and is available to any customer desiring that particular combination of options. As described below, selecting certain options will result in the installation of additional pins in certain locations. Suffix Description Blank No Vout Trim or On/Off Control functions added (no I/O pins installed in the pin 3 and pin 5 positions). The pin length remains at 0.2 inches (5.08 mm). T Add a Vout Trim function on pin 5. No pin 3 installed. C Add an On/Off Control function on pin 3 (with positive polarity). No pin 5 installed. CT Add the On/Off Control function (with positive polarity) on pin 3 and add the Vout trim function on pin 5. N Add an On/Off Control function on pin 3 with negative polarity. No pin 5 installed. NT Add the On/Off Control function with negative polarity on pin 3 and add the Vout trim function on pin 5. L1 Trim the pin length to 0.110 0.010 inches (2.79 0.25mm). This option requires a minimum order quantity. L2 Trim the pin length to 0.145 0.010 inches (3.68 0.25mm). This option requires a minimum order quantity. -C RoHS-6 hazardous substance compliance (does not claim EU RoHS exemption 7b, lead in solder). * Note: Usage of consecutive "C" and "-C" designations is correct for some models. Example: UWR-5/3000-D48AC-C Adaptations There are various additional configurations available on A-Series 7-15W DC/DCs. Because designating each of them with a standard part-number suffix would result in an unmanageable matrix of part numbers, such are designated by MPS and assigned 5-digit "part-number suffixes. UWR-3.3/4250-D48AT-30690 Standard product, 48VIN, 3.3VOUT/4.25A with a VOUT Trim function added in the pin 3 position, with adapted current limit set point to 6.5A min. and with removed Input Overvoltage Shutdown function. UWR-5/3000-D48ACT-30770 UWR-5/3000-D48ACT-30770-Y (RoHS-5) Standard product, 48VIN, 5VOUT/3A. On/Off Control function (positive polarity) on pin 3, VOUT, Trim function added on pin 5. Adaptations: Trim equations are Tyco/Lucent-compatible. Transformer isolation system has been enhanced to meet the basic insulation requirements of UL60950-1/EN60950-1. I/O pins are 25-mil-square Tyco/Lucent compatible. Shielded metal case is connected to +VIN pin 1. Input Overvoltage Shutdown function has been removed. UWR-3.3/4500-D48ANT Standard UWR-3.3/4250-D48A, 48VIN, 3.3VOUT with slightly higher output current (4.5A), negative on/off polarity control and a special competitivecompatible trim. UWR-3.3/4500-D48ANT accepts trim adjustments to 10% of nominal VOUT not to exceed 15W of maximum output power. Users should carefully consider the amount of trim added since excessive positive trim may exceed the overvoltage protection. Excessive negative trim may interfere with proper regulation. UWR-3.3/4500-D48ANST Special trim version. See page 5. UWR-5/3000-D48ANSTHL2-Y UWR-3.3/4500-D48ANTHL2-Y Negative on/off polarity, special trim, conformal coating added, 3.68mm pin length, RoHS-5 compliance (with lead).
