MP4572 - Synchronous Buck Converter

Description

The MP4572 is a fully integrated, fixedfrequency, synchronous step-down converter.

It can achieve up to 2A of continuous output current with peak current control for excellent transient response.

Features

  • include 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 MP4572 offers a very compact solution with a minimal number o.

MP4572 High-Efficiency, 2A, 60V, Fully Integrated Synchronous Buck Converter DESCRIPTION The MP4572 is a fully integrated, fixedfrequency, 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. A 2μA shutdown mode quiescent current makes the MP4572 ideal for battery-powered applications. The MP4572 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode.
