Overview
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  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.
