NXP SSL1623PH开关电源LED驱动方案

NXP 公司的SSL1623PH是开关电源(SMPS)控制器,能直接从通用电压火线(80V-276V)整流电压工作,它集成了6.5Ω和650 V的功率开关,可调频率以方便设计,具有可调过流保护,以及欠压保护,温度保护和短路保护,主要用在LED镇流器,外观照明,LED点照明以及商业照明.本文介绍了SSL1623PH主要特性和优势,方框图以及典型应用电路图.

The SSL1623PH is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal AC mains. It is implemented in the high voltage Easy High Voltage Silicon-On-Insulator (EZ-HV SOI) process, combined with a low voltage Bipolar Complementary Metal Oxide Semiconductor (BiCMOS) process.

The device includes a high voltage power switch and a start-up circuit that operates directly from the rectified mains voltage. A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic LED driver concept possible.
