PT4115E Overview
FEATURES The PT4115E 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 50V and provides an externally adjustable output current of up to 1.5A. The PT4115E includes the power switch and a high-side output current...
