Series Headline Quarter-brick DOSA-Compatible, Isolated DC-DC Converters
Series Description With dimensions of only 2.3 x 0.9 x 0.39 inches, the UWE series open frame DC/DC converters deliver up to 120 Watts in an industry-standard “eighth-brick” through-hole package. This format can plug directly into quarter-brick pin outs. Several standard fi xed-output voltages from 3.3 Vdc to 12 Vdc assure compatibility in embedded equipment, CPU cards and instrument subsystems. The extended 4-to-1 input voltage range (18-75V) is ideal for battery-powered, telecom or portable applications. Very high effi ciency means no fans or temperature deratings in many applications. An optional baseplate extends operation into most conceivable environments.

The synchronous rectifi er design uses the maximum available duty cycle for greatest effi ciency and low power dissipation with no reverse output conduction. 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 automated facility with ISOtraceable manufacturing quality standards. Isolation of 2250 Volts assures safety and fully differential (fl oating) operation for greatest application fl exibility. On-board Sense inputs compensate for line voltage errors at high output currents. Outputs are trimmable within ±10% of nominal voltage.

A wealth of protection features prevents damage to both the converter and outside circuits. Inputs are protected from under voltage and outputs feature 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 compliance.
