SSL2109AT - NXP

SSL2109AT Compact non-dimmable LED driver

The SSL2109AT is a high-voltage Integrated Circuit (IC) for driving LED lamps in general lighting applications. The main benefits of this IC include: • Small Printed-Circuit Board (PCB) footprint and compact solution • High efficiency (up to 95 %) for non-dimmable high power factor solutions • High power factor >0.9 (application dependent) • Ease of integrat.

Features

 LED driver IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply
 Part of a high-efficiency switch mode flyback or buck product family.  Driver-only which can drive an external MOSFET
 Driver that has power-efficient boundary conduction mode of operation with:  No reverse recovery losses in freewheel diode  Zero Current Switching (ZCS) for switch turn-on  Zero voltage or valley switching for switch turn-off  Minimal required inductance value and size
 Suitable for high power factor (>0.9) applications
 Applicable in buck, buck/boost and flyback top.
