MPQ4360GRE-AEC1-P, Switching Voltage Regulators 40V, 6A, Low IQ,Synchronous Step-Down Converter,

MPQ4360 is a configurable-frequency, synchronous, step-down switching converter with integrated, internal high-side and low-side power MOSFETs. The device provides up to 6A of highly efficient output current, with current mode control for fast loop response. The wide 3.3V to 40V input voltage range accommodates a variety of step-down applications in an automotive input environment. High power conversion efficiency across the 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 the output is within 95% to 105% of its nominal voltage. Frequency foldback helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ4360 is available in a QFN-20 (4mmx4mm) package. Applications include automotive infotainment, automotive clusters, automotive telematics and industrial power systems.
