EV28300-G-01A 2-5.5V, 300mA Ultra Low IQ Step-down Regulator plus LDO Step-Down Switcher Evaluation Board QFN12
The MPS EV28300-G-01A is an evaluation board built around the MP28300 for bench characterisation of the device in its intended topology. It operates from a 2 V to 5.5 V input, is rated for 300 mA and switches at 1.5 MHz. The board carries the device in its QFN12 package.
The MP28300 is a monolithic power management unit containing 300mA high efficiency step-down switching converters and a 100mA LDO regulator.

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.
