uint32_t BSP_SMPS_DeInit

(

void

)

DeInitialize the external SMPS component.

Note:

Low power consumption GPIO settings

Return values:

SMPS

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:

SMPS

uint32_t BSP_SMPS_Supply_Disable

(

void

)

Disable the external SMPS component.

Return values:

SMPS	status SMPS_OK: SMPS SWITCH DISABLE OK

uint32_t BSP_SMPS_Supply_Enable	(	uint32_t	Delay,
		uint32_t	Power_Good_Check
	)

Enable the external SMPS SWITCH component.

Parameters:

Delay,:	delay in ms before SMPS SWITCH 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:
