加入技術(shù)交流群
NXP公司的SSL2103是可調(diào)光Greenchip LED驅(qū)動器,支持大多數(shù)調(diào)光解決方案,內(nèi)置的電流具有谷底開關(guān),從而最優(yōu)化效率,具有去磁檢測,超溫保護(OTP),繞組短路保護(SWP)和過流保護(OCP),主要用在LED點和串照明以及背光.本文介紹了SSL2103主要特性和優(yōu)勢,方框圖, 降壓和反激配置圖,以及采用SSL2103的230 V (AC) 17 W 可調(diào)光LED驅(qū)動演示板主要指標(biāo),電路圖和材料清單.
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主要特性和優(yōu)勢:
? Easy migration to existing lighting control infrastructure
? Supports most available dimming solutions
? Optimized efficiency with valley switching managed by a built-in circuitry
? Demagnetization detection
? OverTemperature Protection (OTP)
? Short-Winding Protection (SWP) and OverCurrent Protection (OCP)
? Internal VCC generation allowing start-up from the rectified mains voltage
? Natural dimming curve by logarithmic correction, down to 1 %
? Suitable for flyback and buck applications
SSL2103應(yīng)用:
? SSL applications with various power requirements
? LED modules such as LED spots and down-lights
? LED strings suitable for retail displays, etc.

采用SSL2103的230 V (AC) 17 W 可調(diào)光LED驅(qū)動演示板
This user manual describes a demo board for evaluating an AC mains LED driver with a dimmer for 17 W, PAR38 LEDs using the SSL2103. It describes key features and connections to aid the design of LED drivers for typical applications.
The demo board operates from an AC mains voltage of 230 V (AC). The resulting design is a trade-off between high-power factor, efficiency and dimmer compatibility, combined with high output stability and ELectroMagnetic Compatibility (EMC) compliance.
