Beschreibung

The MP2467 is a high frequency step-down switching regulator with 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 6V to 36V input range accommodates a variety of step-down applications, including those in automotive systems. A 100µA 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 prevents inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation.The MP2467 is available in thermally enhanced SOIC8 package.
