IC revision1

Description

PMP11478 is an isolated active clamp forward converter accepts a voltage range of 24-36V and delivers a 12V output at 2.5A. 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 2.5ms using the stored charge of the output capacitors. The isolation voltage is 2250 VDC meeting basic insulation requirements
