respectively, for SMPS1 and SMPS2. SMPS3 runs at twice the programmed switching frequency.
Switching frequency selection is limited by the minimum on-time. See the Core Switching
Frequency description in the SMPS Design Procedure section.

This slew rate applies to both upward and downward VID transitions, and to the transition from boot
mode to VID mode. Downward VID transition slew rate in skip mode can appear slower because the
output transition is not forced by the SMPS.
The slew rate for startup is fixed at 1mV/µs.
