Beschreibung

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

Eigenschaften

  • 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

Typische Anwendungen

  • LED strings suitable for retail displays, etc.
  • LED modules such as LED spots and down-lights
  • SSL applications with various power requirements
