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_CC 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.
