NXP SSL21083高压8W LED驱动解决方案
NXP公司的SSL2108x系列是高压LED驱动器,集成了300V(SSL21081和 SSL21082)或多或少(SSL21083和SSL21084),开关接通采用零电流开关(ZCS),开关关断采用零电压或谷底电压开关,输出信号采用PWM调制,主要用在输入电压100V/120VAC和230VAC的紧凑型LED照明.本文介绍了SSL2108X主要特性和优势,框图, 基本应用框图,
SSL21083参考板主要指标,电路图和材料清单.
The SSL2108X is a range of high-voltage Integrated Circuits (ICs), intended to drive LED lamps in general lighting applications.
The main benefits of the product family are:
•Small Printed-Circuit Board (PCB) footprint, and compact solution
•High efficiency (up to 95 %)
•Ease of integration
•Low electronic Bill Of Material (BOM)
The product family is made of ICs with a range of internal HV switches for easy power scaling.
The ICs work as boundary conduction mode converters, typically in buck configuration.
