EVQ4485-U-00A 6-36V, 6A Step-Down Converter Evaluation Board QFN26
The MPS EVQ4485-U-00A is an evaluation board built around the MPQ4485 for bench characterisation of the device in its intended topology. It operates from a 6 V to 36 V input and is rated for 6 A. The board carries the device in its QFN26 package.
The MPQ4485 integrates a monolithic step- down switch-mode converter with two USB current-limit switches and charging port identification circuit.

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.
