The MP4460 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 2.5A output with current mode control for fast loop response and easy compensation.?The wide 4.5V to 36V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 100? operational 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. In some applications, such as AM radio and ADSL applications, in which the device is sensitive to frequency band, the MP4460 can avoid the related EMI problem by setting the frequency at 4MHz. The MP4460 is available in a small 3x3mm QFN10 package.
