High Power Factor LED Controller with HV Start-up

REV: 00

General Description

The LD7832 is a buck solution with high PFC control for

LED lighting. It features HV start-up, easy to design with

minimum cost and PCB size. The device operates in

transition(TM) mode and integrates with complete safety

requirement protections.

With HV start-up technology, high power factor and TM

control, the system is enabled to achieve high PF and

high efficiency to meet most of the international standard.

The LD7832 also features LED open protection (OVP),

LED short protection (ZCD UVP), over current protection

(OCP), CS short protection (CSSP), open feedback

protection and over temperature protection (OTP). It

makes the circuit designers easily to meet most safety

requirements in either normal or abnormal test.

Features

 Built-in 600V HV startup

 High power factor controller integrated

 High efficiency transition mode operation

 Accurate current regulation

 Wide range of UVLO (17.5 VON and 8 VOFF)

 VCC OVP (VCC over Voltage Protection)

 ZCD OVP (Adj. Output Voltage Protection)

(Option: with ZCD OVP disabled, LD7832A)

 ZCD UVP (ZCD under voltage protection)

 OCP (Cycle by cycle current limit)

 CSSP (CS short protection)

 Open feedback protection

 OTP (Over Temperature Protection)

 250/-500mA Driving Capability

Applications

 LED Lamp、LED bulb Application
