MPQ4323 is a frequency-configurable (350KHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal highside and low-side power MOSFETs. The device provides 3A of highly efficient output current with peak current mode control. The wide 3.3V to 36V input voltage range and 42V load dump tolerance accommodates a variety of step-down applications in automotive input environments. A 1µA shutdown current (ISD) allows the device to be used in battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency under light-load conditions to reduce the switching and gate driving losses. An open drain power good signal indicates that output is within 94.5% to 105.5% of its nominal voltage. The MPQ4323 is available in QFN-12 (2mmx3mm) and QFN-12 (3mmx4mm) packages. Applications include automotive infotainment systems, automotive clusters, advanced driver assistance systems and industrial power systems.
