Automotive, Wide 60V, 2A Fully Integrated Synchronous Buck Converter

The MPQ4572 is a fully integrated, fixed-frequency, synchronous step-down converter. It can achieve up to 2A of continuous output current with peak current control for excellent transient response. The wide 4.5V to 60V input voltage range synchronous switching regulator accommodates a variety of automotive step down applications. The device’s low 40μA quiescent current makes it ideal as an off-battery regulator.
