SSL2129AT Dimmable LED controller IC Rev. 3 10 April 2013 Product data sheet 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 NXP Semiconductors Dimmable LED controller IC Brownout protection Mains phase cut dimmable LED driver solution: Supports both leading and trailing-edge dimmers Easy external temperature protection with a single NTC Open output protection using external components Compatible with wall switches with built-in indication light during standby IC lifetime easily matches or surpasses LED lamp lifetime Input current distributed evenly over the phase, reducing required output capacitor size and bleeder dissipation 3. Applications The SSL2129AT is intended for mains dimmable compact LED lamps for single mains input voltages. Mains input voltages include 100 V, 120 V and 230 V (AC). The external components determine the power range. 4. Quick reference data Table 1.
