EV Board Features
See the MIC22705YML datasheet for detailed
explanations of these functions.
Enable/Delay (EN/DLY)
Enable/Delay allows delayed turn on of the MIC22705.
Install a capacitor in location C6 to increase the start-up
delay of the MIC22705.
Shutdown Input (SHDN)
SHDN allows enable/disable of the MIC22705 with an
external logic signal. To activate the shutdown feature,
install components into the locations labeled Q1 and R5
(component recommendations are listed in the Bill of
Materials later in this document). With the components
installed, force SHDN high to disable the MIC22705, and
low to allow the MIC22705 to operate normally.
Delay (DELAY)
DELAY allows a delayed Power Good output (PG)
indication. Install a capacitor in location C8 to increase the
Power Good delay timing of the MIC22705.

Ramp Control (RC)
Ramp control allows slowing the slew rate of the
MIC22705 output. Increase the value of capacitor C7 to
reduce the slew rate.
Power Good Output (PG)
Open drain output PG pulls low when the output voltage of
the MIC22705 is out of specification. PG is pulled up to V
by a 47.5kΩ resistor.
