Other Parts Discussed in Thread: BQ25756, TPS25750, , TPS25751
Hello forum,
We are currently designing a bidirectional charger using the BQ25756 charger and the TPS25750 power delivery controller for a 10S battery. After reviewing the block diagram (as seen in the image), we are considering whether it's possible to eliminate the TPSM365 buck converter, connect PPHV to PP5V, and utilize the buck-boost converter to step down the battery voltage from 42V to 5V. The 3.3V supply for the integrated circuit would be provided by a separate regulator.
Any insights or suggestions regarding this modification would be greatly appreciated.
Thank you in advance for your assistance.
Best regards,
Manuel
