MPQ4462DN-LF Monolithic Power Systems

MPQ4462-AEC1 3.5A, 4MHz, 36V, Step-Down Converter AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ4462 is a high-frequency, step-down, 120A Quiescent Current switching regulator with an integrated, high-side, Wide 3.8V-to-36V Input Range high-voltage, power MOSFET. It provides a 3.5A 150m Internal Power MOSFET output with current-mode control for fast loop Up to 4MHz Programmable Switching response and easy compensation. Frequency Stable with a Ceramic Capacitor The wide 3.8V-to-36V input range accommodates Internal Soft-Start a variety of step-down applications, including Internally-Set Current Limit without a Current those in an automotive input environment. A Sensing Resistor 120A operational quiescent current allows for battery-powered applications. Output Adjustable from 0.8V to 30V Available in 3mm3mm QFN10 and SOIC8E Switching-frequency scaling allows for high Packages. power-conversion efficiency over a wide load Available in AEC-Q100 Qualified Grade 1 range by scaling down the switching frequency at light loads to reduce the switching and gate APPLICATIONS driving losses. High-Voltage Power Conversion The frequency foldback prevent inductor-current Automotive Systems runaway during startup, and thermal shutdown Industrial Power Systems provides reliable and fault tolerant operation. Distributed Power Systems The MPQ4462 can operate at up to 4MHz for Battery Powered Systems EMI-sensitive applications, such as AM radio All MPS parts are lead-free and adhere to the RoHS directive.
