SSL21081 Description
The SSL21081/SSL21083 are a range of high-voltage Integrated Circuits (ICs) for driving LED lamps in general mains non-dimmable lighting applications. The main benefits of these products are: Small Printed-Circuit Board (PCB) footprint, and pact solution High efficiency (up to 95 %) Ease of integration Low electronic Bill Of Material (BOM) These ICs incorporate a 300 V or 600 V MOSFET.
