MONOLITHIC POWER SYSTEMS (MPS) MPQ4313GRE-5-AEC1-P Datasheet & Stock

MPQ4313 is a frequency-programmable, synchronous, step-down switching regulator with integrated internal high-side and low-side power MOSFET. It provides up to 3A of highly efficient output with current mode control for fast loop response. The wide 3.3V to 45V input voltage range accommodates a variety of step-down applications in an automotive input environment. A 1.7μA shutdown mode quiescent current allows the part to be used in battery-powered applications. High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency in light-load conditions to reduce the switching and gate driver losses. An open-drain power good signal indicates whether the output is within 95% to 105% of its nominal voltage. The MPQ4313 is available in a QFN-20 (4mmx4mm) package. Typical applications include automotive infotainment, automotive clusters, advanced driver assistance systems and industrial power systems.
