SSL2109 Description
The SSL2109 series is a range of high-voltage Integrated Circuits (IC) for driving LED lamps in general lighting applications. The main benefits of this IC include: Small Printed-Circuit Board (PCB) footprint, and pact solution High efficiency (up to 95 %) Ease of integration and many protection.
SSL2109 Key Features
- LED controller IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply
- Part of a high-efficiency switch mode buck driver product family
- 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
- Direct PWM dimming possible
- Fast transient response through cycle-by-cycle current control
- Negligible AC mains ripple in LED current and minimal total capacitor value
- No over or undershoots in the LED current
