The Future of Analog IC Technology MP4561 1.5A, 2MHz, 55V Step-Down Converter DESCRIPTION The MP4561 is a high frequency step-down switching regulator with integrated internal highside high voltage power MOSFET. It provides 1.5A output with current mode control for fast loop response and easy compensation. The wide 3.8V to 55V input range accommodates a variety of step-down applications, including those in automotive input environment. A 12µA shutdown mode supply 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.
