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