NXP Semiconductors SSL2109T

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 compact 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 dV/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.
