SSL21084T Datasheet Greenchip Drivers

Manufacturer: NXP Semiconductors

Overview: SSL21081T/2T/3T/4T GreenChip drivers for LED lighting Rev. 2 — 6 December 2011 Preliminary data sheet 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The SSL2108X is a range of high-voltage Integrated Circuits (ICs), intended to drive LED lamps in general lighting applications.

The main benefits of the product family are: • • • • Small Printed-Circuit Board (PCB) footprint, and pact solution High efficiency (up to 95 %) Ease of integration Low electronic Bill Of Material (BOM) The product family is made of ICs with a range of internal HV switches for easy power scaling.

The ICs work as boundary conduction mode converters, typically in buck configuration.

Key Features

  • LED driver IC family driving strings of LEDs from a rectified mains supply.
  • High-efficiency switch mode buck driver product family:.
  • Drivers with integrated 300 V (SSL21081 and SSL21082) or 600 V (SSL21083 and SSL21084) power switches.
  • Controller with power-efficient boundary conduction mode of operation with:.
  • No reverse recovery losses in freewheel diode.
  • Zero Current Switching (ZCS) for turn-on of switch.
  • Zero voltage or valley switching for turn-on of swit.
