Low Cost: Isolated 3W Flyback Reference Design

Description

The PMP30313 is a low cost isolated flyback reference design.  It supplies 12V @ 0.25A from universal mains. It's primary-side regulated: therefore the voltage loop is closed on the primary side by means of an auxiliary winding. It is also protected against output short circuit.

Features
  • Simple opto-less isolated flybackSuitable for low power applications or bias supplyThe controller integrates 700V FET and cycle-by-cycle limits the current in the transformerOverload: overcurrent and over-temperature protected
