Learn about our Evaluation Kit
Product Description
The EV9486A-N-00A Evaluation Board is designed to demonstrate the performances of MPS’ MP9486A which is a 4.5V-to-100V-input step-down converter.
The MP9486A 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 of typical 3.5A. MPS’s proprietary feedback control scheme minimizes the number of external components.
This board is configured for 5V step-down application. It can support 1A continuous load or 2A pulse load. The circuit requires only a minimal number of readily-available, standard, external components.

100V Input, 3.5A, Switching Current Limit Step-Down Converter
The MP9486A 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 3.5A, 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 MP9486A to be used in battery-powered applications.
The MP9486A is available in a SOIC-8 package with an exposed pad.
