NXP SSL2103 17W调光Greenchip LED驱动方案
NXP公司的SSL2103是可调光Greenchip LED驱动器,支持大多数调光解决方案,内置的电流具有谷底开关,从而最优化效率,具有去磁检测,超温保护(OTP),绕组短路保护(SWP)和过流保护(OCP),主要用在LED点和串照明以及背光.本文介绍了SSL2103主要特性和优势,方框图, 降压和反激配置图,以及采用SSL2103的230 V (AC) 17 W 可调光LED驱动演示板主要指标,电路图和材料清单.
The SSL2103 is a Switched Mode Power Supply (SMPS) controller IC that operates in combination with a phase cut dimmer directly from the rectified mains. It is designed to drive LED devices. The device includes a circuit to allow direct start-up from the rectified mains voltage.
For dimmer applications, an integrated dedicated circuitry optimizes the dimming curve.
• SSL2101: fully integrated LED driver for lamps up to 10 W
• SSL2102: fully integrated LED driver for lamps up to 25 W
• SSL2103: gives the application designer flexibility to:
Use an external power switch to allow the IC to provide any power
Use an external bleeder transistors to provide extended dimmer interoperability
SSL2103主要特性和优势:
Easy migration to existing lighting control infrastructure
Supports most available dimming solutions
