SSL21082AT Mains dimmable LED driver IC Rev. 6 — 3 October 2013 Product data sheet 1. General description The SSL21082AT is a high-voltage Integrated Circuit (IC) for driving retrofit LED lamps in general lighting applications. It enables the implementation of a very compact low-cost system solution. The IC has an integrated internal HV switch and work as Boundary Conduction Mode (BCM) buck converter. The SSL21082AT is supplied by a start-up bleeder resistor, a dV/dt supply using capacitive coupling from the drain or any other auxiliary supply. The IC supply current is low. An internal clamp limits the supply voltage. The IC has an accurate output current control and can be operated using Pulse-Width Modulation (PWM) dimming. In addition, several protection features are available such as easy external temperature feedback. The main benefits of this IC include: • • • • • • • • Small Printed-Circuit Board (PCB) footprint and compact solution High efficiency (up to 90 %) 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 modes Single inductor used for non-isolated configurations because of internal demagnetization detection and dV/dt supply The IC is designed to start up directly from the HV supply using an internal high-voltage current source. An internal clamp limits the supply voltage. SSL21082AT NXP Semiconductors Mains dimmable LED driver IC 2. Features and benefits „ LED driver IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply „ Power-efficient boundary conduction mode 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 overshoot or undershoot 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) ‹ Brownout protection ‹ Output Short Protection (OSP) „ Mains phase cut dimmable LED driver solution: ‹ Supports both leading-edge 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 SSL21082AT is intended for mains dimmable compact LED lamps for single mains input voltages. Mains input voltages include 100 V (AC) and 120 V (AC).
