Allegro Microsystems 1-Channel Buck Converter, Adjustable Output, 3 A, 2000 kHz, QFN 16-Pin A4403GEUTR-T

Allegro Microsystems A4403GEUTR-T is a single-channel buck converter designed to efficiently regulate voltage in industrial and consumer electronic applications. Featuring an adjustable output current of up to 3 A and a high switching frequency of 2000 kHz, this device provides stable and efficient power management suitable for various power supply designs.

The buck converter supports a wide input voltage range from 9 V minimum to 46 V maximum, making it flexible for integration in systems exposed to variable power sources. Packaged in a compact QFN 16-pin surface mount package measuring 4 mm by 4 mm and a height of 750 μm, it enables space-constrained PCB layouts.

With a low quiescent current of 100 μA, the component minimizes power loss during idle states, contributing to energy-efficient system designs. It operates reliably across a temperature range from -40°C to 105°C, suitable for demanding industrial or automotive environments not requiring automotive standard certification.
