Description

General part information

MP4560 Series

The MP4560 is a high frequency step-down switching regulator with integrated internal highside high voltage power MOSFET. It provides 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 at light load condition to reduce the switching and gate driving losses. The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation.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 3x3 10-Pin QFN and SOIC8 with Exposed Pad Packages
