The Future of Analog IC Technology DESC RIPTION The MP2560 is a high frequency step-down switching regulator with an i ntegrated internal high-side high volta ge power MOSFET. It provides 2.5A outpu t with current mode control for fast lo op response and easy compensation. The wide 4.5V to 42V input range accommodat es a variety of step-down applications, including those in an automotive input environment. A 12µA shutdown mode qui escent current allows use in battery-po wered applications. High power conversi on efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to r educe the switching and ga

te driving losses. The frequency foldbac k helps prevent inductor current runawa y during startup and thermal shutdown p rovides reliable, fault tolerant operat ion. By switching at 4MHz, the MP2560 i s able to prevent EMI (Electromagnetic Interference) noise problems, such as t hose found in AM radio and ADSL applica tions. The MP2560 is available in small 3mm x 3mm QFN10 and thermally enhanced SOIC8 packages.
