SSL2103 Description
SSL2103 is a Switched Mode Power Supply (SMPS) controller IC designed for LED lighting applications. It is an extension of the NXP SSL2101/SSL2102 product platform, allowing easy design of derivative applications. When used in bination with a phase cut dimmer connected directly to a rectified mains, it provides dimmability to the application.
SSL2103 Key Features
- Easy migration to existing lighting control infrastructures, TRIAC and transistor dimmers
- patible with most dimming solutions
- Optimized efficiency with valley switching managed by built-in circuitry
- Built-in demagnetization detection
- Built-in OverTemperature Protection (OTP)
- Short-Winding Protection (SWP) and OverCurrent Protection (OCP)
- Internal VCC generation allowing start-up from rectified mains voltage
- Natural dimming curve by logarithmic correction, optimized for human eye response, down to 1 %
SSL2103 Applications
- SSL2101: fully integrated LED driver for lamps up to 10 W
- SSL2102: fully integrated LED driver for lamps up to 25 W
