SSL21081T Description
The SSL2108X is a range of high-voltage Integrated Circuits (ICs), intended to drive LED lamps in general lighting applications. The main benefits of the product family are: Small Printed-Circuit Board (PCB) footprint, and pact solution High efficiency (up to 95 %) Ease of integration Low electronic Bill Of Material (BOM) The product family is made of ICs with a range of internal HV switches for easy power scaling.
SSL21081T Key Features
