NXP SSL2101 12W调光LED驱动方案
NXP公司的SSL2101是开关电源(SMPS)控制器,可直接从火线整流电压工作,并集成了相位调光器.器件包括高压功率开关,以及允许直接从整流的火线电压工作的电路和给相位调光器供电的高压电路.主要用于高达15W的LED模块驱动.本文介绍了SSL2101主要特性,方框图,典型应用电路图以及12W调光LED驱动器电路,输入电压230VAC和120VAC所用的材料清单(BOM).
The SSL2101 is a Switched Mode Power Supply (SMPS) controller IC that operates directly from rectified mains and also in combination with a phase cut dimmer. It is designed to drive LED devices. The device includes a high-voltage power switch and a circuit to allow start-up directly from the rectified mains voltage. Furthermore the device includes high-voltage circuitry to supply the phase cut dimmer.
For dimmable applications, integrated dedicated circuitry optimizes the dimming curve.
