Requirements
The MIC28510 evaluation board requires o
power supply with at least 10A current ca
linear regulator, which includes a Zener an

housekeeping (V
load can either be a passive or an active load.
Precautions
The MIC28510 evaluation board does not have
reverse polarity protection. Applying a negative
voltage to the PVIN and GND terminals may damage
the device. The maximum PVIN of the board is rated
at 75V. Exceeding 75V on the PVIN could damage the
device.
