User Module Datasheet: Floating Load Buck Regulator Datasheet FLBUCK V 1.1 (CY8CLED0xD, CY8CLED0xG)

Last Updated: 
Oct 15, 2012
Version: 
1.1

Features and Overview

  • Highly efficient hysteretic current-mode buck converter
  • 50 kHz to 2 MHz effective switching frequency range
  • Ideal topology for LED applications
  • 4 independent channels
  • Independent configurable linear and PWM dimming
  • Optional current or temperature protection

The Floating Load Buck Regulator User Module (FLBUCK) allows you to create a fully functional LED driver with dimming and temperature protection based on a current mode buck converter. It also can be used as a general purpose buck converter that regulates the output current, not the voltage.
