The MP9486 is a high-voltage, step-down, switching regulator that delivers up to 1A of continuous current to the load. It integrates a high-side, high-voltage, power MOSFET with a current limit of 2.5A, typically. The wide 4.5V to 100V input range accommodates a variety of step-down applications, making it ideal for automotive, industry, and lighting applications. Hysteretic voltage-mode control is employed for very fast response. MPS’s proprietary feedback control scheme minimizes the number of required external components. The switching frequency can be up to 1MHz, allowing for small component size. Thermal shutdown and short-circuit protection (SCP) provide reliable and fault-tolerant operations. A 170µA quiescent current allows the MP9486 to be used in battery-powered applications. The MP9486 is available in a SOIC-8 package with an exposed pad.

EV9486-N-00A Evaluation Kit 1A,100V Wide Input Buck Converter EV Board
The EV9486-N-00A Evaluation Board is designed to demonstrate the performances of MPS’ MP9486 which is a 4.5V-to-95V-input, 1A-output step-down converter.
The MP9486 employs hysteresis voltage control method to provide fast response to line or load transient. It integrates a high-side high voltage power MOSFET with a current limit higher than 1.7A. MPS’s proprietary feedback control scheme minimizes the number of external components.
This board is configured for 5V step-down application. The circuit requires only a minimal number of readily-available, standard, external components
