Figure 10-2 shows the General Settings that can be used to configure the following:

• Vout settings, power-good limits, and margin voltages
• OC Fault, OC Warn and Fault response
• OT Fault, OT Warn (Die Temperature) and Fault response
• Vin on and off UVLO
• On and Off Config
• Soft Start (Output rise time), other Turn-On Timing and Turn-Off Timing
• Switching frequency
• Compensation

After clicking Write to Hardware to make changes to one or more configurable parameters, the changes can be committed to nonvolatile memory by clicking Store Config to NVM. This action prompts a pop-up, and if confirmed, the changes are committed to nonvolatile memory to store all the modifications in non-volatile memory.

Both the Stack Controller device (U1_P1) and the Stack Follower device (U1_P2) are tied to same bus interface. In a two-phase stacking system, the stack controller receives and responds to all PMBus communication and follower devices do not need to be connected to the PMBus. If the stack controller receives commands which require updates to the PMBus values of one or all of the followers, the stack controller relays these commands to the followers. All commands on this tab are for PHASE = 0xFF.
