SSL2103T Datasheet PDF - Silergy

●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 %

● Suitable for flyback and buck applications
