MP2452
MP2452 is Step-Down Converter manufactured by Monolithic Power Systems.
DESCRIPTION The MP2452 is a high frequency (1MHz) stepdown switching regulator with integrated internal high-side high voltage power MOSFET. It provides up to 1A highly efficient output current with current mode control for fast loop response. The wide 3.3V to 36V input range acmodates a variety of step-down applications in automotive input environment. A 3µA shutdown mode quiescent 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. Frequency fold-back helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. The MP2452 is available in the 2mm x 3mm QFN8 package. 1A, 36V, 1MHz Step-Down Converter FEATURES - 1A Continuous Load Current - 130 µA Operating Quiescent Current - Wide 3.3V to 36V Operating Input Range - 500 mΩ Internal Power MOSFET - 1MHz fixed Switching Frequency - Internally pensated - Stable with Ceramic Output Capacitors - Internal Soft-Start - > 90% Efficiency - +0.794V FB Reference Voltage - Output Adjustable from +0.794V to 33V - 3µA Low Shutdown Supply Current - 2mm x 3mm QFN8 Package APPLICATIONS - High Voltage Power Conversion - Automotive Systems - Industrial Power Systems - Distributed Power Systems - Battery Powered Systems “MPS” and “The Future of Analog IC Technology” are Registered Trademarks of Monolithic Power Systems, Inc..
