WINSEMI WS3215

The WS3215 is a continuous conduction mode inductive step-down converter.designed for driving single or multiple series LED efficiently from a voltage source higher than the total LED chain voltage. The device operates from an input supply between 8V and 30V and provides an external adjustable output current of up to 1.5A.Depending upon supply voltage and external components, the WS3215 can provide more than 10 watts of output power. The WS3215 includes the power switch and a high-side output current sensing circuit .which uses an external resistor to set the nominal average output current, and a dedicated DIM input accepts either a DC voltage or a wide range of pulsed dimming.
