SSL5031BTS - Compact high power factor/low-THD buck LED driver

General Description

The SSL5031BTS 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 SSL5031BTS 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.

SSL5031BTS Compact high power factor/low-THD buck LED driver IC Rev. 2 — 11 March 2015 Product data sheet 1. General description The SSL5031BTS 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 SSL5031BTS is designed for high power factor/low-THD applications. The SSL5031BTS operates in Boundary Conduction Mode (BCM) with on-time regulation. Operating in BCM provides a constant output current control with high accuracy. Adaptive switching frequency gives freedom to choose the inductor, which enables the optimization of inductor size, efficiency and EMI.
