Output Voltage Tracking and
Sequencing
The IR3622A can accommodate a full spectrum
of user programmable tracking and sequencing
options using Track, Seq, Enable and Power
Good pins.
Through these pins both simple voltage tracking
such as that required by the DDR memory
In general the R A and R B set the output voltage
for the first output and R C and R D set the output
voltage for the second output.
For simultaneous vs. ratiometric, RE and RF can
be selected according to the table below:
Track Pin
application or more sophisticated sequencing
such as ratiometric or simultaneous can be
implemented.
The Seq pin controls the internal current sources
to set the power up or down sequencing. Toggle
this pin high for power up, and toggle this pin low
for power down.
The Track pin is used to determine the second
channel output for either ratiometric or
simultaneous by using two external resistors.
Figure 9 shows how these pins are configured for
different sequencing mode.
