The V15 input voltage can be supplied directly by an SBC or Voltage regulator. The S32K3x8 devices provide two options to derive the V15 regulator from the 5V or 3.3V supply.

Option 1: A DC/DC converter (SMPS) regulator can be implemented by connecting the external components (PMOS, inductor, diode) shown in the figure above, at pins VDD_DCDC,

PMOS_CTRL, and VSS_DCDC. In this case, VRC_CTRL must not be connected. VDD_DCDC must be connected to the VDD_HV_A or VDD_HV_B, supply voltage. In this

VRC_CTRL pin must be connected to the base of the transistor. In this case, VDD_DCDC, PMOS_CTRL must not be connected. VSS_DCDC must be connected to MCU GND.

Option 2: A linear regulator can be implemented by connecting a bipolar NPN transistor from the VDD_HV_A or VDD_HV_B, supply voltage shown as VC_BJT in the figure above. The

COUT_V15

In this option, COUT_V15 is specified in Recommended decoupling capacitors.

option, COUT_V15 is specified in SMPS regulator electrical specifications.
