SMPS is active, initiating a transition to a new output
voltage level. If this mode of DAC control is used, con-
nect SUS low. Change D0 –D5 together, avoiding
greater than 50ns skew between bits. Otherwise, incor-
rect DAC readings may cause a partial transition to the
wrong voltage level, followed by the intended transition
to the correct voltage level, lengthening the overall tran-
sition time. The available DAC codes and resulting out-
put voltages are shown in Table 4.
Suspend Mode (S0, S1, SUS)
When the CPU enters low-power suspend mode, the
processor sets the regulator to a lower output voltage
to reduce power consumption. The MAX8720 includes
a suspend-mode input (S0, S1) and a digital SUS con-
trol input. The suspend voltage is programmed using
the 4-level S0, S1 inputs (Table 5). The suspend volt-
age adjustment range is from 0.275V to 0.650V.
