SSL2103: Dimmable Greenchip controller for LED lighting 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? 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 applicationsSSL2103应用:? SSL applications with various power requirements? LED modules such as LED spots and down-lights? LED strings suitable for retail displays, etc.图L2103方框图图L2103亮度控制框图图L2103降压配置应用电路图图L2103反激配置应用电路图SSL2103演示板This user manual describes a demonstration (demo) board for evaluating an AC mains LED driver with a dimmer for 14 W, A55 LEDs using the SSL2103. It describes key features and connections to aid the design of LED drivers for typical e demo board operates from an AC mains voltage of 230 V (AC) at 50 Hz. The resulting design is a trade-off between high-power factor, efficiency and dimmer compatibility.
