EV4458DQT-00A 1A Step-Down Converter Evaluation Board QFN10
The MPS EV4458DQT-00A is an evaluation board built around the MP4458 for bench characterisation of the device in its intended topology. It is rated for 1 A and switches at 4 MHz. The board carries the device in its QFN10 package.
The EV4458DQT-00A is an evaluation board for the MP4458, a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET.

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.
