NXP SSL152x 5W LED驱动方案
NXP 公司的SSL152x系列是开关电源（SMPS）控制器，采用高压EZ-HV SOI工艺和低压BiCMOS工艺，能直接从火线整流中工作。器件包括高压功率开关和起动电路。LED驱动器的功率高达15W，通用AC电压（80V-276V），可调整的频率，待机功耗低于100mW，主要用在改进型LED灯，LED镇流器，建筑物轮廓照明和隧道信号照明。本文介绍了SSL152x 主要特性，方框图，典型配置框图以及SSL1523 5 W LED驱动器技术指标，演示板电路图和材料清单（BOM）。
SSL1523 high power factor 5 W LED driver for universal mains
SSL152x SMPS ICs for mains LED drivers
The SSL152x family is a Switched Mode Power Supply (SMPS) controller IC that operates
directly from the rectified universal mains. It is implemented in the high-voltage EZ-HV SOI process, combined with a low-voltage BiCMOS process. The device includes a high-voltage power switch and a circuit for start-up directly from the rectified mains voltage.
A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic concept for solid state lighting applications possible.
The SSL152x can operate in applications with a power range of up to 15 W. For a power range between 15 W and 25 W the SSL1623PH is the best choice. For LED powers above 25 W the SSL1750 can be used.
