7.5.7 PMIC_VBUSOTG

PMIC_VBUSOTG is the output of the PWR_USB_SW in the STPMIC1A. It is designed to

power USB OTG port or USB Type-C. The input of the switch is connected to the

PMIC_BSTOUT internal to the STPMIC1A. The output voltage of the PWR_USB_SW is

approximately equal to the PMIC_BSTOUT.

7.5.8 PMIC_SWOUT

PMIC_SWOUT is the output of the PWR_SW internal to the STPMIC1A. The input of the switch

is brought out to the PMIC_SWIN pin. The output voltage of PMIC_SWOUT will be about equal

to the input voltage provided on PMIC_SWIN.

7.6 Internal Power

The OSD32MP15x has power rails generated by the STPMIC1A that are used internally by the

OSD32MP15x. While some of the output voltages of the regulators can be adjusted, they

should not be adjusted. Adjusting the voltages on these rails will cause the OSD32MP15x

device not to function.

These power pins should not be uses to power external components. Doing so can prevent the

OSD32MP15x from functioning properly. However, they may be used for debugging /

monitoring the system and as reference voltage outputs.

7.6.1 VDD_CORE

VDD_CORE is generated by Buck1 in the STPMIC1A. It provides the core power to the

STM32MP15x integrated into the OSD32MP15x. By default, its voltage is 1.2V. See Table 7-1

for required STPMIC1A configuration of this voltage rail.

7.6.2 VDD_DDR

VDD_DDR is generated by Buck2 in the STPMIC1A. It provides the power to the DDR memory

integrated into the OSD32MP15x. By default, its voltage is 1.1V. See Table 7-1 for required

STPMIC1A configuration of this voltage rail.

7.6.3 VDD

VDD is generated by Buck3 in the STPMIC1A. It provides the power to the VDD Power domain

of the STM32MP15x integrated into the OSD32MP15x. By default, this voltage is set to 3.3V.

The VDD output is used to set the I/O voltage for the STM32MP15x. Therefore, the output

voltage can be modified to support both 1.8V and 3.3V I/O operation.
