The Future of Analog IC Technology MPQ2451 Industrial/Automotive-Grade 36V, 2MHz, 0.6A Step-Down Converter AEC-Q100 Qualified DESCRIPTION The MPQ2451 is a high frequency, step-down, switching regulator with an integrated highvoltage high-side power MOSFET. It efficiently provides up to a 0.6A output with current-mode control for fast loop response. The wide 3.3V-to-36V input range accommodates a variety of automotive step-down applications, and the 3μA shutdown-mode quiescent current allows use in battery-powered applications. The MPQ2451 achieves high power-conversion efficiency over a wide load range by scaling down the switching frequency under light-load condition to reduce the switching and gate driving losses. Frequency fold-back prevents inductor current runaway during start-up.
