The SSL2101 is a Switched Mode Power Supply (SMPS) driver 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 high-voltage power switch, a circuit to allow start-up directly from the rectified mains voltage and a high-voltage circuitry to supply the phase cut dimmer.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 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 %
  • Limited external components required because of the high integration level
  • Thermal enhanced SO16 wide body package
  • Suitable for flyback and buck applications
