MP4571GQB - Synchronous Buck Converter

This page provides the datasheet information for the MP4571GQB, a member of the MP4571 Synchronous Buck Converter family.

Description

The MP4571 is a fully integrated, fixedfrequency, synchronous step-down converter.

It can achieve up to 1A of continuous output current with peak current control for excellent transient response.

Features

  • including built-in soft start, enable control, and a power good indicator. High duty cycle and low-dropout mode are provided for automotive cold crank conditions. In addition, the chip provides overcurrent protection with valley current detection, which helps prevent current runaway. It also has hiccup short-circuit protection (SCP), input undervoltage lockout (UVLO), and auto-recovery thermal protection. With internal compensation, the MP4571 offers a very compact solution with a minimum number.

MP4571 High-Efficiency, 1A, 60V, Fully Integrated Synchronous Buck Converter DESCRIPTION The MP4571 is a fully integrated, fixedfrequency, 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. A 2μA shutdown mode quiescent current makes it ideal for battery-powered applications. The MP4571 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode, and is available in a 12-pin QFN package.
