Product Summary

The MP2565DN-LF-Z 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 50V input range accommodates a variety of step-down applications, including those in an automotive input environment. 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 MP2565DN-LF-Z is able to prevent EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications. The MP2565DN-LF-Z is available in small 3mm x 3mm QFN10 and thermally enhanced SOIC8 packages.
