Hello S32K388,
I am using the S32K388 for one of my applications. The V11 is meant to be supplied by a last mile regulator NMOS from V15. However I would like to supply this 1.5V from a external DC/DC converter. Is that feasible?
Best regards,
Jules
Hello @JulesW ,
Based on the S32K388 power architecture, V11 must be generated using the external NMOS last-mile regulator from the V15 rail, as described in the Hardware Design Guidelines.
However, if your question is whether the 1.5 V V15 rail itself can be supplied from an external DC/DC converter, then this is feasible. This is also the approach used on the S32K388 EVB, where one jumper option is that the 1.5 V rail is generated externally by the PMIC.
Best regards,
Pavel
