UST Models www.murata-ps.com 3W, Single Output DC/DC Converters PRODUCT OVERVIEW FEATURES  Lowest cost! Highest reliability!  100% SMT-on-pcb, including magnetics  100% automatically assembled  Standard "DIP" package and pinouts  Fully isolated, 1000Vdc guaranteed  5, 12 or 15 Volt outputs  Choice of 3 wide-range inputs: 4.5-9 Volts 9-18 Volts 18-72 Volts Rarely has a Series of low-power DC/DC converters been defined by both low cost and Murata Power Solutions' made-in-the-USA quality and reliability. Our new UST Series of single-output DC/DC’s achieves this best-of-both-worlds status by implementing a proven circuit architecture (170-200kHz flyback design) as a full, SMT-on-pcb assembly (including surface-mount magnetics) that is truly 100% automatically assembled. Packaged in miniature 1.25" x 0.8", DIP-like plastic packages (UL94V-0 rated) and requiring no external components, UST Series DC/DC’s bring true componentlike convenience to designers of today’s distributed power systems. Output voltages are 5, 12 or 15 Volts. Input voltage ranges are 4.5-9V ("D5" models), 9-18V ("D12" models) or an ultra-wide 18-72V ("D48" models). UST DC/DC’s are fully isolated (1000Vdc guaranteed) and include input (pi type) and output filters within their package. Output transient response is a quick 200µsec, while output ripple and noise are typically 75mVp-p. These rugged modules are fully encapsulated with a thermally conductive potting compound that contributes to their outstanding moisture/vibration resistance and impressive MTBF. They operate over the full –40 to +75°C temperature range without derating. All models have been thoroughly characterized (electrically, mechanically and thermally), qualified (including HALT), and EMI/EMC tested. Additionally, they are certified to UL1950, CSA 22.2 No. 950 and IEC950. Murata Power Solutions' UST Model 3W DC/ DC’s are excellent selections for telecom/datacom, computer and process-control applications demanding small size, low cost and high reliability. If required, their design "flexibility" allows for easy modification to your application-specific requirements.  Guaranteed efficiencies to 73%  –40 to +75°C full-power operation  Internal input/output filtering  UL1950/C22.2 No. 950/IEC950 certified  Modifications and customs for OEM’s +VOUT +VIN COMMON –VIN PWM CONTROLLER OPTO ISOLATION REFERENCE & ERROR AMP 　 Figure 1.
