Monolithic Power Systems, Inc. Switching Voltage Regulators MP9486GN

The MP9486GN is a high-voltage, step-down switching regulator capable of delivering up to 1A of continuous current. It features a wide input voltage range from 4.5V to 100V, making it suitable for various applications including automotive, industrial power supplies, and high-power LED drivers. The device employs hysteretic voltage-mode control for fast response and integrates a high-side power MOSFET with a current limit of 2.5A. With a maximum switching frequency of 1MHz, the MP9486GN allows for smaller external components. It includes essential protection features such as thermal shutdown and short-circuit protection, ensuring reliable operation. The quiescent current is low at 170µA, which is advantageous for battery-powered applications. The regulator is packaged in a SOIC-8 format with an exposed pad for improved thermal performance.
