Standard C4 Deeper Sleep Exit: When exiting
deeper sleep (DPRSLPVR pulled low) while the out-
put voltage is regulating to the deeper sleep
voltage, the MAX17021/MAX17082/MAX17482
immediately activate all enabled phases and ramp
the output voltage to the LFM DAC code provided
by the processor at the slew rate set by R TIME . The
controller blanks PWRGD, PHASEGD, and CLKEN
until 20 μs after the transition is completed. See
?
IMVP-6+ 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 MAX17021 remains in 1-
phase skip mode and ramps the output voltage to
the LFM DAC code provided by the processor at 1/4
the slew rate set by R TIME . The controller blanks
PWRGD, PHASEGD, and CLKEN until 20μs after the
transition is completed. See Figure 7.
