FT833BD-DGB - High Precision PSR Constant Current LED Driver

Download the FT833BD-DGB datasheet PDF. This datasheet also covers the FT833S11-RB variant, as both devices belong to the same high precision psr constant current led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

FT833xxx is a high precision primary-side feedback and regulation constant current driver for LED lighting applications.

It is designed to work in inductor current discontinuous conduction mode (DCM) and is especially suitable for flyback converter under universal input.

Key Features

  • Built-in 650V power MOSFET.
  • PSR constant current control without secondary sense and feedback circuit.
  • No auxiliary winding for sensing and supplying.
  • Ultra low operating current for high efficiency.
  • Universal input voltage.
  • ±3% LED current accuracy.
  • Choice for maximum duty cycle and OVP voltage.
  • Precision OVP voltage for best LED open circuit protection.
  • LED short circuit protection.
  • CS resistor short circuit protection.
  • VCC under-voltage.
