QEB100 single output DC/DC converters provide up to 100 watts of output power in an
industry standard quarter-brick package and footprint. These units are specifically
designed to meet the power needs of low-voltage silicon. All models feature a wide input
range, trimmable output voltage and a 30A current rating. Remote sense and remote
on/off facilities are included as standard, and the converters are comprehensively
protected against over-current, over-voltage and over-temperature conditions. The
QEB100 converters are especially suited to telecom, networking and industrial application.

Note
1. Maximum output deviation is 10% inclusive of trim. If remote sense is not being used, the +V sense should be connected to its corresponding
+OUTPUT and likewise the –sense should be connected to its corresponding –OUTPUT.
2. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V models. Power mate
suggest: Nippon chemi-con KMF series, 220F/100V, ESR 90m.
3. The negative / positive logic and pin length are optional ( see table ). The pin voltage is referenced to negative input.
4. Heat sink is optional and P/N7G-00297G-00307G-00317G-0032.
5. The QEB100 meets level A and level B conducted emissions only with external components connected before the input pin to the converter.
6. Typical value at nominal input voltage and full load
7. BASEPLATE GROUNDINGBase-plate should be grounded at one of the four screw bolts prior to operation.
8. The converter is provided by basic insulation.
