Product Overview

The UCC28740EVM-525 is an Evaluation Module for evaluate the operation and performance of UCC28740, a 10W offline discontinuous mode (DCM) flyback converter that provides constant-voltage (CV) and constant-current (CC) output regulation. It uses optical coupler feedback for tight voltage regulation and improved the transient response to large load steps and primary side control for accurate constant current regulation. The UCC28740 controller uses frequency modulation, peak primary current modulation, valley switching and valley skipping in its control algorithm in order to maximize efficiency over the entire operating range.
  • Universal AC input, 5V/2.1A output
  • <20mW No load power
  • >80% Average efficiency
  • Opto-coupled feedback for constant voltage regulation and fast dynamic response
  • Primary side control for tight constant current performance (±5% Output current regulation)
  • Internal 700V start-up switch to start up the supply directly from the bulk rail
  • Quasi-resonant valley switching operation for highest overall efficiency
  • Protection functions - over-voltage, low line, over-current and short circuit
