PMP10527

Design files

Overview

PMP10527 is a constant current input boost converter for LEDs which utilizes the LM5020 controller. The design features switch current limiting and input under-voltage lockout. Summing feedback for multiple LED strings with constant current regulation allows for wide variation of input voltage.

Features
  • 92V 205mA constant current input, 137V @ 130mA out
  • 18.5W out at 95% peak efficiency
  • 2 layer board
  • Constant current output
  • Summing feedback for multiple strings
