SSL2103T/1,518 NXP

SSL2103 Dimmable Greenchip controller for LED lighting Rev. 2.2 5 December 2011 Product data sheet 1. General description 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 2. Features and benefits 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 V generation allowing start-up from the rectified mains voltage CC Natural dimming curve by logarithmic correction, down to 1 % Suitable for flyback and buck applications 3. Applications SSL applications with various power requirements LED modules such as LED spots and down-lights LED strings suitable for retail displays, etc.SSL2103 NXP Semiconductors Dimmable Greenchip controller for LED lighting 4.
