MP4560DQ-LF-P

MP4560 2A, 2MHz, 55V Step-Down Converter The Future of Analog IC Technology FEATURES DESCRIPTION Wide 3.8V to 55V Operating Input Range The MP4560 is a high frequency step-down 250m Internal Power MOSFET switching regulator with integrated internal high- Up to 2MHz Programmable Switching side high voltage power MOSFET. It provides 2A Frequency output with current mode control for fast loop 140 A Quiescent Current response and easy compensation. Ceramic Capacitor Stable The wide 3.8V to 55V input range accommodates Internal Soft-Start a variety of step-down applications, including Up to 95% Efficiency those in automotive input environment. A 12A Output Adjustable from 0.8V to 52V shutdown mode supply current allows use in Available in 3x3 10-Pin QFN and SOIC8 battery-powered applications. with Exposed Pad Packages High power conversion efficiency over a wide APPLICATIONS load range is achieved by scaling down the switching frequency at light load condition to High Voltage Power Conversion reduce the switching and gate driving losses. Automotive Systems Industrial Power Systems The frequency foldback helps prevent inductor Distributed Power Systems current runaway during startup and thermal Battery Powered Systems shutdown provides reliable, fault tolerant operation. All MPS parts are lead-free and adhere to the RoHS directive. For MPS green status, please visit MPS website under Products, Quality Assurance page. By switching at 2MHz, the MP4560 is able to MPS and The Future of Analog IC Technology are registered trademarks of prevent EMI (Electromagnetic Interference) noise Monolithic Power Systems, Inc. problems, such as those found in AM radio and ADSL applications. The MP4560 is available in small 3mm x 3mm 10-pin QFN and SOIC8 with exposed pad packages.
