put voltage is regulating to the deeper sleep voltage,
the MAX8770/MAX8771/MAX8772 immediately acti-
vate all enabled phases and ramp the output voltage
to the LFM DAC code provided by the processor at
the slew rate set by R
PWRGD, PHASEGD, and CLKEN (forced high
impedance) until 20µs after the transition is complet-
ed. See Figure 5.

• Slow C4 Deeper Sleep Exit: When exiting deeper
sleep (DPRSLPVR high, DPRSTP pulled high) while
the output voltage is regulating to the deeper sleep
voltage, the MAX8770/MAX8771/MAX8772 remain in
1-phase skip mode and ramp the output voltage to the
LFM DAC code provided by the processor at 1/4 the
slew-rate set by R
PHASEGD, and CLKEN (forced high impedance) until
20µs after the transition is completed. See Figure 6.
