Wide Input Active Clamp Forward Converter with Isolated Output
Texas Instruments
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.
