SSL2101

SSL2101 Dimmable GreenChip driver for LED lighting Rev. 4.1 — 31 March 2016 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 VCC generation allowing start-up from the rectified mains voltage  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  Su...
