SSL21082AT - NXP

SSL21082AT Mains dimmable LED driver IC

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 .

Features

 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 .
