SSL2109T
description
The SSL2109T is a high-voltage Integrated Circuit (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 %) for non-dimmable high power factor solutions
- High power factor >0.9 (application dependent)
- Ease of integration and many protection features
- Low electronic Bill Of Material (BOM)
- Highly flexible IC for use in buck, buck/boost and flyback modes
- Single inductor used for non-isolated configurations because of internal demagnetization detection and d V/dt supply
The IC is supplementary to the SSL21081/SSL21083 series but without an internal switch. The IC has been designed to start up directly from the HV supply by an internal high-voltage current source. Thereafter, the d V/dt supply is used with capacitive coupling from the drain, or any other auxiliary supply. This functionality provides full flexibility in the application...
