SSL21083T Compact non-dimmable LED driver IC Rev. 6 — 4 October 2013 Product data sheet 1. General description The SSL21083T is a high-voltage Integrated Circuit (IC) for driving LED lamps in general mains non-dimmable lighting applications. The main benefits are: • • • • Small Printed-Circuit Board (PCB) footprint; compact solution High efficiency (up to 95 %) Ease of integration Low electronic Bill Of Material (BOM) The IC incorporates a 600 V MOSFET. The IC works as boundary conduction mode converters, typically in buck configuration. It 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 function provides full flexibility in the application design. The IC consumes 1.3 mA of supply current with an internal clamp limiting the supply voltage. The IC provides accurate output current control with LED current accuracy within 5 %. The IC can be operated using Pulse-Width Modulation (PWM) current regulation. It has many protection features including easy LED temperature feedback. 2.
