Detailed Description

Description of the Buck Converter Library State Machine library module.

The converter state machine defines the steps required to initialize the power supply chip resources and converter data objects, resets the most recent runtime data in preparation for a power supply startup, monitors the status of fault and control flags and provides sub-functions for powering up the power converter and its control system dependent on which kind of control mode is selected.

The soft-start process includes programmable delays such as Power-On Delay and Power Good Delay including the ramp-up slew rate of the output voltage. In case of system or software errors, the state machine will shut down the power supply and execute a restart attempt.

The complete state machine is encapsulated in and managed by the converter device driver. No user control is required other than calling the high-level 'drv_BuckConverter_Execute' device driver API function at a constant repetition rate.
