SSL2109

SSL2109 series GreenChip controller for LED lighting Rev. 3 — 4 June 2012 Product data sheet 1. General 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 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. Thereafter, the dV/dt supply is used with capacitive coupling from the drain, or any other auxiliary supply. This functionality provides full flexibility in the application design. An internal clamp limits the supply voltage. The IC provides accurate output current control to within 5 % LED current accuracy. The IC can be operated using Pulse-Width Modulation (PWM) dimming and has many protection features including easy LED temperature feedback. www.DataSheet.net/ 2.
