General Description

The SSL5021BTS is a highly integrated, high-precision, non-isolated MOSFET/bipolar buck controller.

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

The SSL5021BTS is designed for low-ripple applications.

Overview

SSL5021BTS Compact low-ripple buck LED driver IC Rev.

2 — 11 March 2015 Product data sheet 1.

Key Features

  • Driving LED strings from a rectified mains supply, low-ripple (< ±5 %).
  • 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 size req.
