Description
The SSL21084AT is a high-voltage Integrated Circuit (IC) for driving retrofit LED lamps in general lighting applications.
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 cur.
