MONOLITHIC POWER SYSTEMS (MPS) MP4436AGR-P Datasheet & Stock

MP4436A is a synchronous, step down switching regulator with a configurable frequency and integrated internal high-side and low-side power MOSFETs. It provides a maximum 6A of highly efficient output, as well as current mode control for a fast loop response. The wide 3.3V to 45V input 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 across 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 that the output is within 93% to 106% of its nominal voltage. Frequency foldback helps prevent inductor current runaway during start-up. Applications include automotive infotainment, automotive clusters, advanced driver assistance systems (ADAS) and industrial power systems.
