PRODUCT OVERVIEW Units are offered with a fixed output voltage and current up to 30 Amps. UEEs operate over a wide temperature range (up to +85 degrees Celsius at moderate airflow) with full rated power. Interleaved synchronous rectifier topology yields excellent efficiency. UEEs achieve these impressive mechanical and environmental specs while delivering excellent electrical performance in an industry standard DOSA compatible through-hole package or surface mount option. The unit is fully protected against input undervoltage, output overcurrent and short circuit. An on-board temperature sensor shuts down the converter if thermal limits are reached and automatically restarts the converter when the fault is removed. An On/Off control input enables phased startup and shutdown in multi-voltage applications. UEEs include a Sense input to correct for ohmic losses. A trim input may be connected to a user’s adjustment potentiometer or trim resistors for output voltage calibration. UEEs include industry-standard safety certifications and BASIC I/O insulation provides input/ output isolation to 2250V. Radiation and conducted emission testing is performed to widely accepted EMC standards. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ F1 +Vin (1) Barrier +Vout (8) External DC Power Source On/Off Control (2) Controller and Power Open = On Reference and Error Amplifier Trim (6) polarity) -Vin (3) -Vout (4) Figure 1.

General conditions for Specifications are +25 deg.C, Vin=nominal, Vout=nominal (no trim installed), full rated load. Adequate airflow must be supplied for extended testing under power. All models are tested and specified with external 1μF and 10 μF paralleled output capacitors and no external input capacitor. All capacitors are low ESR types. Caps are layout dependent. These capacitors are necessary to accommodate our test equipment and may not be required in your applications. All models are stable and regulate within spec under no-load conditions. ➂ Some models are pending safety certification.
