Part Number: TPS6593EVM
1. Our Buck converters trip at a lower current than configured.
Example: if we set the Buck current limit to 2.5A, the buck trips and drops its voltage at 1.9A. Set to 3.5A, trips at 2.9A. It is a consistent ~0.6A difference.
2. We are stuck on the configuration for Buck PGOOD signals. We are aware of the Buck PGOOD window and PGOOD_SELx registers along with the Buck FeedBack pins, however we do not know how to use those to create a trigger condition.
We would like to make a system where Buck PGOOD signals trigger a GPIO high, for external communication.
3. When connecting multiple boards in parallel, we plan to use I2C address 0x28 and 0x2C, toggled using GPIO10. We are able to configure this through the PFSM and verify it is working on independent boards.
However, when we link 2 EVMs in parallel by stacking or jumpers, we get "Programming EEPROM Failed" error messages whenever we try to program to the 0x2C address, while the 0x28 programs are successfully.
