Description

PMP7892 is an isolated active clamp forward converter capable of 42W output power. This design uses the LM5026 active clamp current-mode controller. Output voltage regulation is maintained using an LMV431 shunt regulator and opto-coupler feedback. Schottky rectifiers allow for holdup of 10ms using the stored charge of the output capacitors. The isolation voltage is 2250 VDC meeting basic insulation requirements.
