Design files

Overview

PMP20487 is a hysteretic buck converter reference design which drives LEDs at up to 1A from an input voltage of 9V to 16V. This design uses the TPS92515-Q1 buck LED driver set for a constant off-time of 1μs. Features include integrated N-channel FET, high-side current sense, and shunt FET PWM dimming capability.

Features
  • Compact design
  • Constant off-time architecture
  • Constant average current
  • PWM dimming
  • EMI characterized
