120VAC Input: 48V/12V 32W Flyback Reference Design
Texas Instruments
This reference design uses the UCC28740 flyback controller to generate both 12-V/1-A and 48-V/0.4-A outputs from a 120-V AC input. The valley switching of the UCC28740 allows this design to provide an efficiency of over 89%; no load losses are less than 80 mW.
Features
- Peak efficiency approaches 90%Losses at no load are less than 80 mW120-Vac input generates outputs of 12 V/1 A and 48 V/0.4 ABoard length is approximately 64 mmTest report is available
