Primary-Side Regulated Flyback Converter for Electric Vehicle Battery Monitoring Reference Design
Description
PMP20583 is a primary-side regulated flyback reference design which provides a ground referenced 5V output and an isolated 5V output at up to 80mA each from an input voltage of 37V to 125V. This design uses the UCC28700-Q1 flyback controller for constant voltage and constant current control of the output. Variable frequency operation minimizes standby power at no load. Features include quasi-resonant valley switching for highest efficiency and frequency dithering to improve EMI performance.
