The MP4566 is a high frequency (1MHz) step-down switching regulator with integrated internal high-side high voltage power MOSFET. It provides single 0.6A (or less) highly efficient output with current mode control for fast loop response.? The wide 4.5V to 36V input range accommodates a variety of step-down applications in automotive input environment. The very low shutdown mode 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.? Frequency fold-back helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation.?The MP4566 is available in 2x3mm QFN8 package.
