LD7835 - High Power Factor LED Controller

General Description

The LD7835 is a floating switch buck solution with Active PFC (APFC) control for LED lighting.

It is easy to design with minimum cost and PCB size.

The device operates in transition mode (TM) and integrates with complete safety requirement protections.

Key Features

  • LED open protection (ZCD OVP), LED short protection, over current protection (OCP), and over temperature protection (OTP). It makes the circuit designers easily to meet most of the safety requirements in either normal or abnormal test. Features.
  • High Power Factor Controller Integrated.
  • High Efficiency Transition Mode Operation.
  • Good Accurate Current Regulation.
  • Current Ripple Reduction (CRR) Function.
  • Wide Range of UVLO.
  • Built in OVP o.

Non-isolation Buck Solution LD7835 07/29/2015 High Power Factor LED Controller REV: 01 General Description The LD7835 is a floating switch buck solution with Active PFC (APFC) control for LED lighting. It is easy to design with minimum cost and PCB size. The device operates in transition mode (TM) and integrates with complete safety requirement protections. With power factor correction and TM control, the system is enabled to achieve high PF and high efficiency and to meet most of the international standard. The LD7835 also features LED open protection (ZCD OVP), LED short protection, over current protection (OCP), and over temperature protection (OTP). It makes the circuit designers easily to meet most of the safety requirements in either normal or abnormal test.
