SubState_VRampUp
volatile uint16_t SubState_VRampUp(volatile struct BUCK_CONVERTER_s *buckInstance)
This function ramps up the output voltage to its nominal regulation point.

SubState_PowerGoodDelay
volatile uint16_t SubState_PowerGoodDelay(volatile struct BUCK_CONVERTER_s *buckInstance)
In this function, a counter is incremented until the power good delay has expired.

Function pointer array of buck converter startup sub-states.

Buck converter state machine function pointer array.

The function pointer list BuckConverterRampUpSubStateMachine[] is providing access to a list of state functions. Each function mapped into this array as function pointer represents a self-contained, independent sub-state. The main state machine will call functions from this list in order of their index within the array, starting from '0'. While this list is executed, the calling main state is transparent by passing through the return value of the most recent sub-state. Once all sub-states have been executed, the calling main state will return the COMPLETE flag, allowing the main state machine to move on.

Each function needs to be called by handing over a parameter of type

Each function returns of type unsigned integer:

  • 0 = BUCK_OPSRET_ERROR
  • 1 = BUCK_OPSRET_COMPLETE
  • 2 = BUCK_OPSRET_REPEAT
