NOTE:
1. Maximum output deviation is 10% inclusive of trim. If remote sense is not being used, the +Vsense 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 handling 1A ripple current for 48V
models. Suggest: Nippon chemi-con KMF series, 220μ F/100V, ESR 90mΩ.
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.
5. The OFQ100 meets level A & 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 GROUNDING: Base-plate should be grounded at one of the four screw bolts prior to operation.
8. The converter is provided with basic insulation.
