SMPS controller IC 14-Pin SO T/R

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.

• 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
