SSL2103 Datasheet Smps Controller

Manufacturer: NXP Semiconductors

Overview: SSL2103 SMPS controller IC for dimmable LED lighting Rev. 2 — 25 November 2010 Product data sheet 1.

General Description

SSL2103 is a Switched Mode Power Supply (SMPS) controller IC designed for LED lighting applications.

It is an extension of the NXP SSL2101/SSL2102 product platform, allowing easy design of derivative applications.

When used in bination with a phase cut dimmer connected directly to a rectified mains, it provides dimmability to the application.

Key Features

  • Easy migration to existing lighting control infrastructures, TRIAC and transistor dimmers.
  • Compatible with most dimming solutions.
  • Optimized efficiency with valley switching managed by built-in circuitry.
  • Built-in demagnetization detection.
  • Built-in OverTemperature Protection (OTP).
  • Short-Winding Protection (SWP) and OverCurrent Protection (OCP).
  • Internal VCC generation allowing start-up from rectified mains voltage.
  • Natural dimming curve by logarithmic c.
