| uint32_t BSP_SMPS_Disable | ( | void | ) |
Disable the external SMPS component.
- Note:
- SMPS SWITCH should be disabled first !
- Return values:
-
SMPS status - SMPS_OK: SMPS DISABLE OK - DONE
- SMPS_KO: POWER GOOD CHECK FAILS

| uint32_t BSP_SMPS_Enable | ( | uint32_t | Delay, |
| uint32_t | Power_Good_Check | ||
| ) |
Enable the external SMPS component.
- Parameters:
-
Delay,: delay in ms after enable Power_Good_Check,: Enable Power good check
- Note:
- Power_Good_Check is not used with all boards VoltageRange is not used with MB11312A/S i.e. SMPS only PWR_REGULATOR_VOLTAGE_SCALE2 by board.
- Return values:
-
SMPS status - SMPS_OK: SMPS ENABLE OK
- SMPS_KO: POWER GOOD CHECK FAILS

| uint32_t BSP_SMPS_Init | ( | uint32_t | VoltageRange | ) |
Initialize the external SMPS component.
- Parameters:
-
VoltageRange,: Select operating SMPS supply - DCDC_AND_BOARD_DEPENDENT
- Note:
- VoltageRange is not used with all boards VoltageRange is not used with MB11312A/S i.e. SMPS only PWR_REGULATOR_VOLTAGE_SCALE2.
- Return values:
