This format can plug directly into quarter- brick pin outs. Several standard fi xed-output voltages from Vdc to 12 Vdc assure compatibility in embedded equipment, CPU cards and instrument subsystems.

2 The extended 4-to-1 input voltage range is ideal for battery-powered, telecom or portable applications. Very high effi ciency means no fans or tempera-ture deratings in many applications. An optional baseplate extends operation into most conceivable environments. The synchronous rectifi er design uses the maxi-mum available duty cycle for greatest effi ciency and low power dissipation. These devices deliver low output noise, tight line/load regulation, stable no-load operation and fast load step response. All units are precision assembled in a highly auto-mated facility with ISO-traceable manufacturing quality standards. Isolation of 2250 Volts assures safety and fully differential (fl oating) operation for greatest application fl exibility. On-board Sense terminals compensate for load line voltage errors at high output currents. Outputs are trimmable within 10% of nominal wealth of protection features prevents damage to both the converter and outside circuits.

3 Inputs are protected from under voltage and outputs fea-ture short circuit protection, over current and over temperature shut down. Overloads automatically recover using the hiccup technique upon fault removal. The UWE is certifi ed to standard safety and EMI/RFI approvals. All units meet RoHS-6 hazardous materials OVERVIEWThe UWE Series " Eighth-Brick " DC-DC Converters are high-current Isolated power modules designed for use in high-density system boards.
