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.• 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 an external bleeder transistors to provide extended dimmer interoperability


  •  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
