General Description

The FAN5776 is a synchronous, constant-current LED driver capable of efficiently driving up to ten LEDs in a five-string, two-series LEDs per string configuration.

Optimized for small form-factor applications, the 1.8 MHz switching frequency allows the use of tiny chip inductors and capacitors.

For safety, the device

Key Features

  • Synchronous Current-Mode Boost Converter.
  • Drives up to 10 LEDs at 25 mA Each in a Configuration of 5 Strings of 2 LEDs in Series.
  • 5 LED Outputs: High-Side Current Sources.
  • Two Default Groups of 3x2-LED Channels and 2x2-LED Channels with Individual Enable and PWM Dimming Control to Support Various Lighting.
