230 V in to 180 V out at 200 mA constant-current LED driver reference design

PMP30439

Design files

Overview

This reference design is a low-side Buck (the output voltage is referenced to the positive DC input (+Vin node), not to the GND node). The controller drives a LED string up to 180V with 200mA constant current. The low-side Buck topology simplifies the schematic thanks to direct-driving of the FET, without the need of high-side driver.

Features
  • Simple low-side buck, high-voltage converter
  • Constant current regulation with PWM dimming
  • High conversion efficiency and very compact design
