The SSL2103 is a Switched Mode Power Supply (SMPS) controller 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 circuit to allow direct start-up from the rectified mains voltage. For dimmer applications, an integrated dedicated circuitry optimizes the dimming curve.
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 OverCurrent Protection (OCP)
* Internal VCC generation allowing start-up from the rectified mains voltage
* Natural dimming curve by logarithmic correction, down to 1 %
