40-W, ±15-V flyback with magnetic feedback reference design

PMP22680

Design files

Overview

This reference design generates an isolated ±15 V at 40 W from a 70-V to 120-V DC input voltage. The design uses a magnetic feedback circuit to replace the function of an optocoupler.

Features
  • Use of 100-krad integrated circuits and magnetics
  • Magnetic feedback used to replace the optocoupler
  • Operation with external supply or self bias
Output voltage options PMP22680.1
Vin (Min) (V) 70
