MPQ4560-AEC1 Industrial-Grade, 2A, 2MHz, 55V Step-Down Converter Available in AEC-Q100 DESCRIPTION The MPQ4560 is a high-frequency, step-down, switching regulator with an integrated, highside, high-voltage, power MOSFET. It provides a 2A 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 in light load conditions to reduce the switching and gate driving losses.
