Product Information
Product Overview
NEX40400DDAZ is a high-efficiency step-down converter with low operating quiescent current. The wide 4.5V to 40V input range is suitable for a variety of power step-down applications in industrial and automotive environments. 0.3µA ultralow shutdown supply current allows use in battery-powered applications. The high power conversion efficiency across a wide load range is achieved by folding down the switching frequency at light load conditions, reducing the switching losses. The frequency foldback helps to prevent inductor current runaway during start-up and to allow operation in both high conversion ratio and low drop-out cases. The thermal shutdown provides reliable and robust operation. Target applications include industrial distributed power systems, grid infrastructure: smart E-meter, battery-powered home appliances, and white goods.
