In the first case, driving RC with a voltage from 0V to

VREF programs the output voltage between 0 and 100%

of the nominal set voltage.

In the second case, the external capacitor sets the ramp

up and ramp down time of the output voltage. The time

is given by

−

RAMP

⋅

where TRAMP is the time

from 0 to 100% nominal output voltage.

RC pin cannot be left floating. Use a minimum capacitor

value of 220pF or larger.

Sequencing and Tracking Examples

There are four distinct variations which are easily

implemented using the MIC22600. The two sequencing

variations are Delayed and Windowed. The two tracking

variants are Normal and Ratio Metric. The following

diagrams

illustrate

methods

for

connecting

two

MIC22600’s to achieve these requirements.
