PMP22056

Design files

Overview

This reference design is a non-isolated flyback topology that takes a universal AC input (90 VAC to 275 VAC) and outputs 5 V at 550mA. The design is an ultra-small form factor and uses a custom transformer.

Features
  • Ultra-compact at 25-mm x 25-mm x 10-mm (height)
  • Universal input
  • EMI tested
Output voltage options PMP22056.1
Vin (Min) (V) 90
Vin (Max) (V) 275
Vout (Nom) (V) 5
Iout (Max) (A) .55
Output Power (W) 2.75
Isolated/Non-Isolated Non-Isolated
Input Type AC
Topology Flyback- DCM

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
