AM623: AM6231电源适配问题 VDD_CORE电压选取0.85V Rfb电阻在哪里焊接？

Rfb电阻 R150在sch里面没有看到？

文档有误，请参考下面的文档。(2) The AM62 starter kit comes with the TPS6521904 PMIC by default, supporting VDD_CORE=0.85V. To support VDD_CORE=0.75V, the following changes are required: TPS6521904 PMIC needs to be replaced with TPS6521903, R699 needs to be uninstalled, and R123 needs to be mounted. https://www.ti.com/lit/an/slvafd0b/slvafd0b.pdf对应原理图说明。
