Description

General part information

MPQ4469 Series

MPQ4469 is a step-down switching regulator with an integrated internal high-side power MOSFET and a configurable frequency from 350KHz to 2.5MHz. It provides up to 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. The device is ideal for battery-powered applications due to its extremely low quiescent current. The MPQ4469 employs AAM (advanced asynchronous modulation) mode, which achieves high efficiency in light-load conditions by scaling down the switching frequency to reduce switching and gate-driving losses. High duty cycle and low-dropout mode are provided for automotive cold crank conditions. Overcurrent protection (OCP) is employed to prevent the inductor current from running away. Typical applications includes automotive and industrial power systems. The MPQ4469 is available in a QFN-20 (4mmx5mm) package.
