Product Introduction

Overview

The LM3409QHVMYX/NOPB is a high-voltage P-channel MOSFET (PFET) controller designed for step-down (buck) current regulators, particularly suited for high-power LED drivers. This device is part of the LM3409 family from Texas Instruments and is AEC-Q100 Grade 1 qualified, making it suitable for automotive applications. It features a wide input voltage range, high-side differential current sensing, and a thermally enhanced 10-pin HVSSOP package. The LM3409QHVMYX/NOPB is ideal for use as a constant current source for driving LEDs with forward currents up to 5 A.
