Overview

PT4115 30V, 1.
2A Step-down High Brightness LED Driver with 5000:1 Dimming GENERAL DESCRIPTION The PT4115 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage.
The device operates from an input supply between 6V and 30V and provides an externally adjustable output current of up to 1.
2A.
Depending upon the supply voltage and external components, the PT4115can provide more than 30 watts of output power.
The PT4115 includes the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average outpu...
