MPQ4576GQBE - Fully Integrated Synchronous Buck Converter

Download the MPQ4576GQBE datasheet PDF. This datasheet also covers the MPQ4576 variant, as both devices belong to the same fully integrated synchronous buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MPQ4576 is a fully integrated, fixedfrequency, synchronous step-down converter.

The device can achieve up to 600mA of continuous output current with peak current control for excellent transient response.

Key Features

  • include built-in soft start, enable control, and power good indication. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions. The MQ4576 provides over-current protection (OCP) with valley current detection to avoid current runaway. It also provides hiccup shortcircuit protection (SCP), input under-voltage lockout (UVLO), and auto-recovery thermal protection. With internal compensation, the MPQ4576 can offer a very compact solution with a minimal number of read.

MPQ4576 600mA, 60V, High-Efficiency, Fully Integrated Synchronous Buck Converter, AEC-Q100 Qualified DESCRIPTION The MPQ4576 is a fully integrated, fixedfrequency, synchronous step-down converter. The device can achieve up to 600mA 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 MPQ4576 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode.
