NAME
FUNCTION
Low-Voltage Logic Input Signal. This is usually the logical complement of the DPRSLPVR signal.
However, there is a special condition during C4 exit when both DPRSTP and DPRSLPVR could
temporarily be simultaneously high. If this happens, the MAX17410 reduces the slew rate to 1/4
the normal (R TIME -based) slew rate for the duration of this condition. The slew rate returns to
normal when this condition is exited. Note that only DPRSLPVR and PSI (but not DPRSTP )
determine the mode of operation (PWM vs. skip and number of active phases).

during soft-start and soft-stop transitions. CLKEN is forced low during dynamic VID transitions and
for an additional 20 μs after the transition is completed. CLKEN is the inverse of PWRGD, except for
the 5ms PWRGD startup delay period after CLKEN is pulled low. See the startup timing diagram
(Figure 9). The CLKEN upper threshold is blanked during any downward output voltage transition
that happens when the controller is in skip mode, and stays blanked until the slew-rate-controlled
internal-transition-related PWRGD blanking period is complete and the output reaches regulation.
3.3V Supply Input for the CLKEN CMOS Push-Pull Logic Output. Connect to the 3.0V to 3.6V system
supply voltage.
Exposed Backplate (Paddle) of Package. Internally connected to analog ground. Connect to the
ground plane through a thermally enhanced via.
