Description
General part information
MP2562 Series
The MP2562 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 1A output with current mode control for fast loop response and easy compensation. The wide 4.5V to 50V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 12µA 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. The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 4MHz, the MP2562 is able to prevent EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications. The MP2562 is available in small 3mm x 3mm QFN10 and SOIC8 packages.120µA Quiescent Current(12uA Shutdown) Wide 4.5V to 50V Operating Input Range 460m? Internal Power MOSFET Up to 4MHz Programmable Switching Frequency Stable with Ceramic Capacitor Internal Soft-Start Internally Set Current Limit without external Current Sensing Resistor Up to 95% Efficiency Output Adjustable from 0.8V to 47V Available in 3x3 QFN10 and SOIC8 Packages
