200-V at 400-mA LED lighting from a 24-V input reference design
Description
This boost LED reference design uses the UCC28C42 controller to generate a non-isolated output (200-V at 400-mA) from a DC input (20-V - 28-V). The UCC28C42 provides a cost effective and precise constant-current regulation and is able to drive a 400-mA LED string up to a LED voltage of 200-V. An open LED protector circuitry provides overvoltage protection.
