Typical Application Circuit
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
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. Applying a
voltage of 0.3V or lower to the DIM pin turns the output off
and switches the device into a low current standby state.
