Description

General part information

MPQ4560 Series

The MPQ4560 is a high-frequency, step-down, switching regulator with an integrated, high-side, high-voltage, power MOSFET. It provides a 2A output with current mode control for fast loop response and easy compensation. The wide 3.8V-to-55V input range accommodates a variety of step-down applications, including those in automotive input environment. A 12µA shutdown mode supply current allows use 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. Frequency foldback prevents inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 2MHz, the MPQ4560 can prevent electromagnetic interference problems, such as those found in AM radio and ADSL applications. The MPQ4560 is available in small 3mm x 3mm QFN10 and SOIC8E packages.Guaranteed Industrial Automotive Temperature Range Limits Wide 3.8V-to-55V Operating Input Range 250m? Internal Power MOSFET Up to 2MHz Programmable Switching Frequency 140µA Quiescent Current Ceramic Capacitor Stable Internal Soft-Start Up to 95% Efficiency Output Adjustable from 0.8V to 52V Available in QFN10 (3mmx3mm) and SOIC8E Packages
