MPQ4560DQ-LF-P

MPQ4560-AEC1 Industrial-Grade, 2A, 2MHz, 55V Step-Down Converter Available in AEC-Q100 FEATURES DESCRIPTION Guaranteed Industrial Automotive The MPQ4560 is a high-frequency, step-down, Temperature Range Limits switching regulator with an integrated, high- Wide 3.8V-to-55V Operating Input Range side, high-voltage, power MOSFET. It provides 250m Internal Power MOSFET a 2A output with current mode control for fast Up to 2MHz Programmable Switching loop response and easy compensation. Frequency The wide 3.8V-to-55V input range 140A Quiescent Current accommodates a variety of step-down Ceramic Capacitor Stable applications, including those in automotive input Internal Soft-Start environment. A 12A shutdown mode supply Up to 95% Efficiency current allows use in battery-powered Output Adjustable from 0.8V to 52V applications. Available in QFN10 (3mmx3mm) and High-power conversion efficiency over a wide SOIC8E Packages load range is achieved by scaling down the AEC-Q100 Qualified switching frequency in light load conditions to APPLICATIONS reduce the switching and gate driving losses. High-Voltage Power Conversion Frequency foldback prevents inductor current Automotive Systems runaway during startup and thermal shutdown Industrial Power Systems provides reliable, fault tolerant operation. Distributed Power Systems By switching at 2MHz, the MPQ4560 can Battery Powered Systems prevent electromagnetic interference problems, All MPS parts are lead-free and adhere to the RoHS directive.
