SMPS1 and SMPS2 can be used in parallel in dual-phase mode to be able to multiply the output current by 2, and the converter is named SMPS1&2. The naming SMPS1 and SMPS2 is used when the bucks are configured as a separate buck converters.
Additional information about how this parameter is specified is located inSection 6.2.2.
This slew rate refers to the rate at which the output voltage changes from one voltage level to another voltage after startup is complete.
