Power Phasing Architectures
Observe the simpli?ed timing diagrams below. There are many possible power
phasing architectures and these are just some examples to help you analyze
your system. Each application will be different. Multiple output voltages may
require more complex timing than that shown here.
These diagrams illustrate the time and slew rate relationship between two
typical power output voltages. Generally the Master will be a primary power
voltage in the system which must be present ?rst or coincident with any
Slave power voltages. The Master output voltage is connected to the Slave’s
Sequence input, either by a voltage divider, divider-plus-capacitor or some
other method. Several standard sequencing architectures are prevalent. They
are concerned with three factors:
? The time relationship between the Master and Slave voltages
? The voltage difference relationship between the Master and Slave
? The voltage slew rate (ramp slope) of each converter’s output.
For most systems, the time relationship is the dominant factor. The voltage
difference relationship is important for systems very concerned about possible
latchup of programmable devices or overdriving ESD diodes. Lower slew rates
avoid overcurrent shutdown during bypass cap charge-up.
Figure 11. Proportional or Ratiometric Phasing (Identical V OUT Time)
Figures 12 and 13 show both delayed start up and delayed ?nal voltages
for two converters. Figure 12 is called “Inclusive” because the later starting
POL ?nishes inside the earlier POL. The timing in Figure 12 is more easily built
using a combined digital sequence controller and the Sequence/Track pin.
Figure 13 is the same strategy as Figure 12 but with an “exclusive” timing
relationship staggered approximately the same at power-up and power-down.
In Figure 10, two POL’s ramp up at the same rate until they reach their
different respective ?nal set point voltages. During the ramp, their voltages
are nearly identical. This avoids problems with large currents ?owing between
logic systems which are not initialized yet. Since both end voltages are differ-
ent, each converter reaches it’s setpoint voltage at a different time.
Figure 12. Staggered or Sequential Phasing—Inclusive (Fixed Delays)
Figure 10. Coincident or Simultaneous Phasing (Identical Slew Rates)
Figure 11 shows two POL’s with different slew rates in order to reach differ-
ing ?nal voltages at about the same time.

(Fixed Cascaded Delays)
