Description

The PMP4444 is an universal AC input, 65W output flyback converter with primary-side regulation(PSR) enabled by the UCC28630D high-power flyback controller. The PSR solution eliminates the need for optocouplers and secondary-side feedback components creating a small, low BOM cost system. The design's dual outputs of 12V/3A and 24V/1.3A with excellent +/-5% cross-regulation performance is ideal for applications such a monitors and televisions.

Features
  • Peak efficiency of 87.5% @ 230Vac full load
  • Transformer designed for +/-5% cross regulation
  • AC input brown out protection
  • Ultra slim design,10mm height
  • Passes compliance for EMI regulations
