NXP SSL2103 12W调光E27装饰灯LED照明解决方案

NXP公司的SSL2103是用于调光LED照明的开关电源(SMPS)控制器.作为一款多用途AC/DC LED照明控制器,SSL2103具有更宽的功率适用范围和更好的调光兼容性,令其适用于可调及不可调LED照明灯。SSL2103除具有SSL2101和SSL2102的功能和性能外,还可以满足更高功率的应用,在正常工作温度下的寿命可以超过75000小时。演示板外形尺寸可以应用于E27、GU10或者PARx 灯。本文介绍了SSL2103主要特性和优势, 方框图, 亮度控制框图, 降压和反激配置框图以及230 V 12 W E27装饰灯LED驱动器演示板主要特性,电路图和材料清单.

SSL2103: SMPS controller IC for dimmable LED lighting

SSL2103 is a Switched Mode Power Supply (SMPS) controller IC designed for LED lighting applications. It is an extension of the NXP SSL2101/SSL2102 product platform, allowing easy design of derivative applications.

When used in combination with a phase cut dimmer connected directly to a rectified mains, it provides dimmability to the application.

In dimmer applications, 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 permitting the:

control of an external power switch to allow the IC to provide any power

control of external bleeder transistors to provide extended dimmer interoperability

The device includes a circuit that allows start-up directly from the rectified mains voltage.

SSL2103主要特性和优势:

Easy migration to existing lighting control infrastructures, TRIAC and transistor Dimmers

Compatible with most dimming solutions

Optimized efficiency with valley switching managed by built-in circuitry

Built-in demagnetization detection

Built-in OverTemperature Protection (OTP)

Short-Winding Protection (SWP) and OverCurrent Protection (OCP)

Internal VCC generation allowing start-up from rectified mains voltage

Natural dimming curve by logarithmic correction, optimized for human eye response,down to 1 %

SSL2103应用:

The SSL2103 is suitable for various power requirements including:

Retro-fit lamps

LED modules such as LED spots and down-lights

LED strings suitable for retail displays etc.
