Description

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.

Features
  • Wide input voltage range
  • Low cost solution
  • BJT drive
  • Over current, over voltage and short-circuit protected
  • Test report available
