High Light-Load Efficient 120VAC Input: 25W/5VDC Reference Design with 4 POL Outputs
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 AIncludes 3.3-V/2-A: 2.5-V/2-A: 1.5-V/3-A: 1-V/5-A outputsFlyback output (5 V) peak efficiency greater than 85%Flyback output dissipates 61 mW at no-loadHelps meeting Energy Star requirements
