NXP Semiconductors SSL2109
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 compact solution High efficiency (up to 95 %) Ease of integration and many protection features Low electronic Bill Of Material (BOM) The IC is supplementary to the SSL2108 series but without an internal switch. The IC range has been designed to start up directly from the HV supply by an internal high-voltage current source.FEATURES AND BENEFITS
● 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
● Controller that has power-efficient boundary conduction mode of operation with:
● No reverse recovery losses in freewheel diode
