MPQ4572

High-Efficiency, 2A, 60V, Fully Integrated, Synchronous Buck Converter, AEC-Q100 Qualified

Datasheet

Description

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 accommodates a variety of step-down applications in an automotive input environment. The device’s 2μA shutdown mode quiescent current makes it ideal for battery-powered applications.

The MPQ4572 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. High-duty cycle and low-dropout mode are provided for automotive cold crank conditions.

The chip provides over-current protection (OCP) with valley-current detection to avoid current runaway. It also has hiccup short-circuit protection (SCP), input under-voltage lockout (UVLO), and auto-recovery thermal protection.

With internal compensation, the MPQ4572 can offer a very compact solution with a minimal number of readily available, standard external components. It is available in a QFN-12 (2.5mmx3mm) package.
