Description
The SSL2102 is a Switched Mode Power Supply (SMPS) driver IC that operates in combination with a phase cut dimmer directly from rectified mains. It is designed to drive LED devices. The device includes a high-voltage power switch, a circuit to allow direct start-up 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
Features
- 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 Over Current 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 SO20 wide body package
- Suitable for flyback and buck applications
Typical applications
- LED modules such as LED spots and down-lights
- SSL retro-fit lamps (for example: GU10, E27)
- SSL applications below 25 W
- LED strings suitable for retail displays, etc.
