NXP SSL2101 / SSL2102 LED Driver ICs


The NXP SSL2101 / SSL2102 is a Switched Mode Power Supply (SMPS) controller IC that operates in combination with a phase cut dimmer directly from rectified mains. It is designed to drive LED devices. The NXP SSL2101 / SSL2102 includes a high-voltage power switch and a circuit to allow direct start-up from the rectified mains voltage. Furthermore the device includes high-voltage circuitry to supply the phase cut dimmer.

For dimmer applications, integrated dedicated circuitry optimizes the dimming curve.

NXP SSL2101 / SSL2102 LED Driver Applications

The SSL2101/2 is suitable for high efficiency and high power factor SSL applications below 25 W, these include:
  • SSL retro-fit lamps (e.g. GU10, E27) up to 10W for the SSL2101 and up to 15W for the SSL2102
  • LED modules, separate power supplies, e.g. LED spots, down-lights up to 15W for the SSL2101 and from 15W to 25W for the SSL2102
  • LED strings, e.g. retail display up to a maximum of 15W for the SSL2101 and up to 25W for the SSL2102
NXP SSL2101 / SSL2102 LED Driver Features
  • Easy migration to existing lighting control infrastructure, TRIAC and transistor dimmers
  • Supports majority of available dimming solutions
  • Valley switching efficiency is optimized by dedicated built-in circuitry
  • Built-in demagnetization detection
  • The IC has Over Temperature Protection (OTP) built-in
  • Short-Winding Protection (SWP) and Over Current Protection (OCP)
  • The IC has internal VCC generation that allows start-up from rectified mains voltage
  • Natural dimming curve by logarithmic correction
