EV9485-N-00A 4.5-100V, 500mA Input Step-Down Converter EV Board Evaluation Board SOIC8

The MPS EV9485-N-00A is an evaluation board built around the MP9485 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 100 V input, is rated for 500 mA and switches at 1 MHz. The board carries the device in its SOIC8 package.

The EV9485-N-00A Evaluation Board is designed to demonstrate the performances of MPS' MP9485 which is a 4.5V-to-100V-input, 500mA-output step-down converter.

Evaluation Board

Design Notes

The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
