WS3215 Description
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 ponents, the WS3215 can provide more than 10 watts...
