120VAC Input 5V/250mA Flyback Converter With BJT Switch Reference Design
Texas Instruments
This reference design creates a 5V at 250mA from a 120VAC Input. The UCC28720 primary side controller with a BJT power switch provides a low cost design. It is important to note the outputs are only functionally (not for safety) isolated from the input.
