SSL2101T - Dimmable LED driver IC


This device is no longer available.  Please see the EOL notice.

  • Easy migration to existing lighting control infrastructure
  • Thermal enhanced SO16 wide body package
  • Suitable for flyback and buck applications
  • 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

Typical Application


The SSL2101T 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.
