Other Parts Discussed in Thread: TPS745
Since VDD_CORE can be supplied either by a 0.75V or a 0.85V supply, is there anything prohibiting to power the AM64xx with the LP87334D instead of the LP873364 and removing the additional TPS745? This means, VDD_CORE, VDDR_CORE, VDDA_0P85_*, VDD_DLL_MMC0 and VDD_MCU0 would be powered by the BUCK0 dc-dc converter (of course with filtering of the analog voltages).
The accordingly modified Figure 2 of the application brief "slvaes0-Powering the AM64xx with the LP8733xx PMIC" is shown below:
Thank a lot for your help,
best regards,
Bernd
