PMP7902, 1.25W Isolated Flyback Converter for Analog/Digital Power

PMP7902, 1.25W Isolated Flyback Converter for Analog/Digital Power. PMP7902 is an Isolated Flyback converter utilizing the LM5001 non-synchronous current-mode regulator I.C. The design accepts an input voltage of 4.5V to 5.5V and provides an isolated 5V output capable of supplying 0.25A of current to the load. The design uses an off-the-shelf VERSAPAC transformer, providing 500V of operational isolation between primary and secondary. A precision shunt regulator provides a tight control of the output voltage using an optocoupler to cross the isolation barrier
