Modes of Operation
TABLE 2. VR1 MODES OF OPERATION
Table 3 shows VR2 operational modes, programmed by the PS
command. VR2 operates in 1-phase CCM in PS0 and PS1, and
enters 1-phase DE mode in PS2 and PS3 mode.

Dynamic Operation
VR1 and VR2 behave the same during dynamic operation. The
controller responds to VID changes by slewing to the new voltage
at a slew rate indicated in the SetVID command. There are three
SetVID slew rates, namely SetVID_fast, SetVID_slow and
SetVID_decay.
SetVID_fast command prompts the controller to enter CCM and

to actively drive the output voltage to the new VID value at a
minimum 10mV/μs slew rate.

SetVID_slow command prompts the controller to enter CCM and
to actively drive the output voltage to the new VID value at a
minimum 2.5mV/μs slew rate.
SetVID_decay command prompts the controller to enter DE
mode. The output voltage will decay down to the new VID value at
a slew rate determined by the load. If the voltage decay rate is
too fast, the controller will limit the voltage slew rate at
SetVID_slow slew rate.

ALERT# will be asserted low at the end of SetVID_fast and
SetVID_slow VID transitions.
VR1 can be configured for 4, 3, 2 or 1-phase operation. Table 2
shows VR1 configurations and operational modes, programmed
by the PWM4, PWM3 pins and the ISEN2 pin status, and the PS
command. For 3-phase configuration, tie the PWM4 pin to 5V. In
this configuration, phases 1, 2 and 3 are active. For 2-phase
configuration, tie the PWM4 and PWM3 pin to 5V. In this
configuration, phases 1 and 2 are active. For 1-phase
configuration, tie the PWM4, PWM3 and the ISEN2 pin to 5V. In

In 3-phase configuration, VR1 operates in 3-phase CCM in PS0
mode. It enters 2-phase CCM operation in PS1 mode. It enters
1-phase DE operation in PS2 and PS3 modes.
In 2-phase configuration, VR1 operates in 2-phase CCM in PS0
and PS1 mode. It enters 1-phase DE mode in PS2 and PS3
modes.
In 1-phase configuration, VR1 operates in 1-phase CCM in PS0
and PS1, and enters 1-phase DE mode in PS2 and PS3.
TABLE 3. VR2 MODES OF OPERATION
FIGURE 13. SETVID DECAY PRE-EMPTIVE BEHAVIOR
Figure 13 shows SetVID Decay Pre-Emptive behavior. The
controller receives a SetVID_decay command at t1. The VR
enters DE mode and the output voltage V O decays down slowly.
At t2, before V O reaches the intended VID target of the
SetVID_decay command, the controller receives a SetVID_fast (or
SetVID_slow) command to go to a voltage higher than the actual
V O . The controller will turn around immediately and slew V O to
the new target voltage at the slew rate specified by the SetVID
command. At t3, V O reaches the new target voltage and the
controller asserts the ALERT# signal.
