Sequencing
The iP1206 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
application and more sophisticated sequencing
such ratiometric or simultaneously 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
simultaneously by using two external resistors.
Fig. 12 shows how these pins are configured for
different sequencing mode.
