Hi Ted,
The Full OPN for the LP87563-Q1 for SemiDrive X9SP is LP875630CRNFRQ1
The latest OTP settings are described in the TRM: https://www.ti.com/lit/pdf/SNVU903
Please note that the current app note for X9SP is being revised, this shows buck2 for LP875630C-Q1 = 3.3V. This should say 1.1V.
The latest version of the power tree should have Buck2 of LP875630C-Q1 powering VDDQ_DRAM, and the external TLV76733-Q21 powering VDDH_3V3 / VDDIO_3V3:

Let me know if there is any confusion I can help clarify.
Best Regards,
Sarah
