The SSL2102 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.

Features and benefits

  • Easy migration to existing lighting control infrastructure
  • Thermal enhanced SO20 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 Over Current 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

Applications

  • SSL applications below 25 W
  • SSL retro-fit lamps (for example: GU10, E27)
  • LED modules such as LED spots and down-lights
  • LED strings suitable for retail displays, etc.
