Product Details
DESCRIPTION The MP2451 is a high frequency (2MHz) stepdown switching regulator with integrated internal high-side high voltage power MOSFET. It provides single 0.6A (or less) highly efficient output with current mode control for fast loop response. 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. FEATURES 130μA Operating Quiescent Current Wide 3.3V to 36V Operating Input Range 500mΩ Internal Power MOSFET 2MHz fixed Switching Frequency Internally compensated Stable with Ceramic Output Capacitors Internal Soft-Start Precision Current Limit Without Current Sensing Resistor > 90 Efficiency Output Adjustable from +0.8V to 0.8xVIN 3μA Low Shutdown Supply Current SOT23-6 and TSOT23-6 Packages APPLICATIONS High Voltage Power Conversion Automotive Systems Industrial Power Systems Distributed Power Systems Battery Powered Systems |
