SSL21081T Overview
The SSL2108X is a range of high-voltage Integrated Circuits (ICs), intended to drive LED lamps in general lighting applications. The main benefits of the product family are: Small Printed-Circuit Board (PCB) footprint, and pact solution High efficiency (up to 95 %) Ease of integration Low electronic Bill Of Material (BOM) The product family is made of ICs with a range of internal HV switches for easy power scaling.
SSL21081T Key Features
- LED driver IC family driving strings of LEDs from a rectified mains supply
- High-efficiency switch mode buck driver product family
- Drivers with integrated 300 V (SSL21081 and SSL21082) or 600 V (SSL21083 and SSL21084) power switches
- No reverse recovery losses in freewheel diode
- Zero Current Switching (ZCS) for turn-on of switch
- Zero voltage or valley switching for turn-on of switch
- Minimal required inductance value and size
- Direct PWM dimming possible
- Fast transient response through cycle-by-cycle current control
- Negligible AC mains ripple at LED current and minimal total capacitor value
