PMP10936

85-265VAC Input, 12V/30W Two-Switch Flyback Reference Design

PMP10936

Design files

Overview

The PMP10936 reference design uses the UCC28740 to provide an isolated 12V at 2.5A output.  The UCC24636 is used to control a synchronous recitifer for high efficiency.  The two-switch flyback topology recycles the transformer's leakage energy and provides a further improvement in efficiency.

Features
  • Over  89% average efficiency
  • Less than 40mW standby power consumption
  • Constant current regulation prevents excessive currents in overload
  • Compact size 53mm X 55mm X 23mm (2.1" X 2.15" X 0.9")
