General Description

The MPQ4468 is a frequency-programmable (350kHz to 2.5MHz), asynchronous, step-down switching regulator with an integrated internal high-side power MOSFET.

It provides up to 3.5A of highly efficient output current with current mode control for fast loop response.

The wide 3.3V to 36V input range accommodates a variety of step-down applications in automotive input environments, and is ideal for batterypowered applications due to its extremely low quiescent current.

Overview

DESCRIPTION The MPQ4468 is a frequency-programmable (350kHz to 2.5MHz), asynchronous, step-down switching regulator with an integrated internal high-side power MOSFET.

It provides up to 3.

Key Features

include soft start (SS), external clock sync, enable (EN) control, and a power good (PG) indicator. High duty cycle and low dropout mode are provided for automotive cold-crank condition. Over-current protection (OCP) is employed to prevent the inductor current from running away. Hiccup mode greatly reduces the average current in short-circuit condition. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ4468 is available in a QFN-16 (3mmx4mm) package. MPQ4468 36V, 3.5A, Low-Qu.
