LD7835D - Leadtrend

LD7835D High Power Factor LED Controller

The LD7835D 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 .

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
