DESCRIPTION The MPQ4436/4436A is a frequency programmable, synchronous, step-down switching regulator with integrated internal highside and low-side power MOSFETs. It provides 6A (or less) of highly efficient output, with current mode control for 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 over a wide load range is achieved by scaling down the switching frequency in light-load conditions to reduce the switching and gate driving losses. An open-drain power good signal indicates that the output is within 93% to 106% of its nominal voltage.
