LD7833 - High Power Factor Primary Side Flyback LED Controller

Description

The LD7833 is a primary side regulation Flyback controller with power factor for TRIAC dimmable LED driver.

The LD7833 provides constant current (CC) operation requiring neither photo-coupler nor secondary control circuit.

It minimizes the components counts in a tiny package.

Features

  • High Voltage (700V) Startup Circuit.
  • Transition Mode Operation.
  • High Power Factor.
  • Dimmable by TRIAC dimmer.
  • VCC Over Voltage Pr.

LD7833 2016/12/23 High Power Factor Primary Side Flyback LED Controller With TRIAC Dimming REV: 00 General Description The LD7833 is a primary side regulation Flyback controller with power factor for TRIAC dimmable LED driver. The LD7833 provides constant current (CC) operation requiring neither photo-coupler nor secondary control circuit. It minimizes the components counts in a tiny package. Those make it easy to design for costeffective applications. With high voltage start-up technology, high power factor and TM control, the start-up time and MOSFET switching losses could be minimized efficiently.
