SSL2129AT Overview
Description
The SSL2129AT 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) - Ease of integration and many protection features - Low electronic Bill Of Material (BOM) - Mains phase-cut dimmable using external components - Highly flexible IC for use in buck, buck/boost and flyback modes - Single inductor used for non-isolated configurations because of internal demagnetization detection The IC range has been designed to start up directly from the HV supply using an internal high-voltage current source.
Key Features
- LED driver IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply
- Fast transient response through cycle-by-cycle current control: No over or undershoots in the LED current
- Simple high input power factor solution (>0.9)
