SSL2101 Dimmable GreenChip driver for LED lighting Rev. 4.1 5 December 2011 Product data sheet 1. General description The SSL2101 is a Switched Mode Power Supply (SMPS) driver 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 high-voltage power switch, a circuit to allow start-up directly from the rectified mains voltage and a high-voltage circuitry to supply the phase cut dimmer. 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 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 % Limited external components required because of the high integration level Thermal enhanced SO16 wide body package Suitable for flyback and buck applications 3. Applications SSL applications below 15 W Retro-fit lamps (for example, GU10, E27) LED modules such as LED spots, down-lights LED strings suitable for retail displays, etc.SSL2101 NXP Semiconductors Dimmable Greenchip driver for LED lighting 4.
