1 / 21 page  1. General 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 and dV/dt supply The IC range has been designed to start up directly from the HV supply using an internal high-voltage current source. An internal clamp limits the supply voltage. 2. Features and benefits LED controller IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply Controller provides 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 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) Internal Protection features: UnderVoltage LockOut (UVLO) Leading-Edge Blanking (LEB) OverCurrent Protection (OCP) Internal OverTemperature Protection (OTP) SSL2129AT Dimmable LED controller IC Rev. 2 — 23 October 2012 Product data sheet |
