SSL5511T Description
The SSL5511T is an offline dimmable controller IC, intended to drive dimmable LEDs in general lighting applications, like remote-controlled luminaires and smart lamps. The main benefits of this IC include: Dim level control with either an analog or a digital control input Selectable modes for high power factor or low ripple, allowing a wide LED power range Large dimming range Single stage topology for small PCB...
SSL5511T Key Features
- LED controller IC for driving strings of LEDs or high-voltage LEDs from rectified mains
- High-efficiency switch mode buck, flyback or buck-boost controller driving an external
- Two maximum switching frequencies for highest efficiency or smallest application
- Zero current switching at switch turn-on
- Zero voltage or valley switching at switch turn-on
- Selectable low THD or low LED current ripple modes
- Analog IEC60929 input or digital control input for dimming
- Continuous (analog) regulation of LED current in both the dimming control modes
- Dim curve selection based on the control input type
- No binning on LED forward voltage required
