138-264VACin: 3.5V/0.12A Primary-Side Regulated Flyback with Bipolar Power Device Reference Design


The PMP10218 reference design provides an isolated 3.5V/0.12A output from a wide input range (138-264VAC). The UCC28722 uses primary-side regulation which eliminates the need of an optical coupler. This design delivers additional cost savings by employing a bipolar power switch.
