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 lightingSSL2103 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 en used in combination with a phase cut dimmer connected directly to a rectified mains, it provides dimmability to the 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 powercontrol of external bleeder transistors to provide extended dimmer interoperabilityThe device includes a circuit that allows start-up directly from the rectified mains L2103主要特性和优势:Easy migration to existing lighting control infrastructures, TRIAC and transistor DimmersCompatible with most dimming solutionsOptimized efficiency with valley switching managed by built-in circuitryBuilt-in demagnetization detectionBuilt-in OverTemperature Protection (OTP)Short-Winding Protection (SWP) and OverCurrent Protection (OCP)Internal VCC generation allowing start-up from rectified mains voltageNatural 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 lampsLED modules such as LED spots and down-lightsLED strings suitable for retail displays etc.图L2103方框图图L2103亮度控制框图图L2103降压配置框图图L2103反激配置框图SSL2103 230 V 12 W E27装饰灯LED驱动器演示板SSL2103 230 V 12 W E27 retrofit LED driver demo boardThis SSL2103 user manual is intended for 230 V applications of 12 W demo boards of E27-type (and similar type) retrofit light e circuit implements a Boundary Conduction Mode (BCM) buck converter. It is mains dimmable for both forward phase (triac) dimmers, and reverse phase (transistor) dimmers. It is designed for demonstrating high performance and high efficiency. It produces a 400 mA regulated output current to drive 10 LEDs at a 230 V (AC) input. With the help of an external MOSFET, an efficiency of up to 85 % can be is demo board is connected to a high AC voltage (up to 265 V). Avoid touching the demo board during operation. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using a fixed or variable transformer (Variac) is always D驱动器演示板主要特性:Key reference board features include:?
