The MP1582 is a high frequency step-down switching regulator with integrated internal high-side, high voltage power MOSFET. It provides 2A output with current mode control for fast loop response and easy compensation. The wide 4.5V to 28V input range accommodates a variety of step-down applications, including those in automotive systems. A 100µA 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. The frequency foldback prevents inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. The MP1582 is available in thermally enhanced SOIC8 package.
Wide 4.5V to 28V Operating Input Range Programmable Switching Frequency up to 1.5MHz High-Efficiency Pulse Skipping Mode for Light Loads Ceramic Capacitor Stable Internal Soft-Start Precision Current Limit without a Current Sensing Resistor Up to 95% Efficiency Available in SOIC8 with Exposed Pad Packages
