the MAX17021 remains in one-phase pulse-skipping operation,

the MAX17082/MAX17482 reduce their slew rate to 1/2 of normal.

Shutdown. When SHDN is pulled low, the MAX17021/MAX17082/
MAX17482 immediately pull PWRGD and PHASEGD low, CLKEN
becomes high, all enabled phases are activated, and the output
voltage is ramped down to ground. Once the output reaches 0V,
the controller enters the low-power shutdown state. See Figure 10.
