PT4115EE89E High Brightness LED Driver IC - Now in Stock
We are pleased to announce the availability of the PT4115EE89E from CRM ICBG. This continuous conduction mode inductive step-down converter is designed for efficiently driving single or multiple series-connected LEDs from a voltage source higher than the total LED chain voltage.
Product Overview
The PT4115EE89E operates from an input supply between 6V and 50V and provides an externally adjustable output current of up to 1.5A. It includes the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. A dedicated DIM input accepts either a DC voltage or a wide range of pulsed dimming, making it a highly versatile solution for modern lighting designs.
