Description

This 25-W design uses the UCC28740 in a flyback topology to minimize no-load standby power and the UCC24636 synchronous rectifier controller to minimize power MOSFET body-diode conduction times. The design also features point-of-load converters from the main 5V rail that implement an energy-saving Ecomode. All of the devices within the design work together to improve light-load efficiency to help meet agency approvals.

Features
  • 25-W/5-VDC output power rated at 5 A
  • Includes 3.3-V/2-A, 2.5-V/2-A, 1.5-V/3-A, 1-V/5-A outputs
  • Flyback output (5 V) peak efficiency greater than 85%
  • Flyback output dissipates 61 mW at no-load
  • Helps meeting Energy Star requirements
