产品概述
MPQ4571 is a fully integrated, fixed frequency, synchronous step-down converter. It can achieve up to 1A of continuous output current with peak current control for excellent transient response. The wide 4.5V to 60V input voltage range accommodates a variety of step down applications in an automotive input environment. The device’s 2μA shutdown mode quiescent current makes it ideal in battery-powered applications. The MPQ4571 integrates internal high-side and low-side power MOSFETs for high efficiency without an external schottky diode. It employs advanced asynchronous modulation (AAM) to achieve high efficiency during light-load conditions by scaling down the frequency to reduce switching and gate driver losses. Standard features include built-in soft start, enable control and power good indication. It is available in a QFN-12 (2.5mmx3mm) package. Typical applications include automotive infotainment, automotive lamps and LEDs, automotive motor control and industrial power systems.
