The Future of Analog IC Technology DESCRIPTION The MP4462 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 3.5A output with current mode control for fast loop response and easy compensation. The wide 3.8V to 36V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 120µA 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.
