SSL5031CTS Datasheet Compact high power factor/low-THD buck LED driver

Manufacturer: NXP Semiconductors

Overview: SSL5031CTS Compact high power factor/low-THD buck LED driver IC Rev. 2 — 11 March 2015 Product data sheet 1.

General Description

The SSL5031CTS is a highly integrated, high-precision, non-isolated buck controller with external MOSFET.

It is intended to drive LED lamps in universal mains non-dimmable lighting applications up to 25 W.

The SSL5031CTS is designed for high power factor/low-THD applications.

Key Features

  • Driving LED strings from a rectified mains supply, high power factor/low-THD.
  • Small electronic Bill of Materials (BOM) enabling a compact solution and a small, single layer Printed-Circuit Board (PCB) footprint.
  • Excellent line and load regulation and LED output current accuracy.
  • Efficient BCM operation with:.
  • Minimal reverse recovery losses in freewheel diode.
  • Zero Current Switching (ZCS) and valley switching for switch turn-on.
  • Minimal inductance value and si.
