Rev. 6 — 4 October 2013
Product data sheet
1. General description
The SSL21083AT 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.
