PMP10505

Design files

Overview

PMP10505 is a boost converter for LEDs which utilizes the LM5020-2 controller.  The switching frequency is set to 100 kHz for high efficiency at a nominal output power of 18.5W. The design features switch current limiting, output over-voltage limiting and summing feedback for multiple LED strings. Constant current regulation allows for wide variation of output voltage.

Features
  • Constant current output
  • Summing feedback for multiple strings
  • Allows for wide variation of output voltage
  • Output over-voltage limiting
  • Cycle by cycle switch current limit
  • Synchronizable to external clock
  • Thermal shut down protection
  • Programmable input under-voltage lockout
