General Description
The ET6115 is a continuous conduction mode inductive stepdown converter, designed for driving single multiple series
connected LED efficiently from a voltage source higher than the total LED chain voltage. The device operates from an
input supply between 9V and 36V and provides an externally adjustable output current of up to 1A. Depending upon the
supply voltage and external components, the ET6115 can provide more than 30 watts of output power.
The ET6115 includes the power switch and a highside output current sensing circuit, which uses an external
resistor to set the nominal average output current, and a dedicated DIM input accepts a wide range of pulsed dimming.
The ET6115 is available in SOT895,TO252, SOT23 and MSOP8L packages.
