MP2451DJ-LF-Z Monolithic Power Systems

MP2451 36V, 2MHz, 0.6A Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP2451 is a high frequency (2MHz) step- 130A Operating Quiescent Current down switching regulator with integrated Wide 3.3V to 36V Operating Input Range internal high-side high voltage power MOSFET. 500m Internal Power MOSFET It provides single 0.6A (or less) highly efficient 2MHz fixed Switching Frequency output with current mode control for fast loop Internally compensated response. Stable with Ceramic Output Capacitors Internal Soft-Start The wide 3.3V to 36V input range accommodates a variety of step-down Precision Current Limit Without Current Sensing Resistor applications in automotive input environment. A 3 A shutdown mode quiescent current allows > 90% Efficiency use in battery-powered applications. Output Adjustable from +0.8V to 0.8xV IN 3 A Low Shutdown Supply Current High power conversion efficiency over a wide SOT23-6 and TSOT23-6 Packages load range is achieved by scaling down the switching frequency at light load condition to APPLICATIONS reduce the switching and gate driving losses. High Voltage Power Conversion Frequency fold-back helps prevent inductor Automotive Systems current runaway during start-up. Thermal Industrial Power Systems shutdown provides reliable, fault-tolerant Distributed Power Systems operation. Battery Powered Systems The MP2451 is available in the cost-effective All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For SOT23-6 and TSOT23-6 packages.
