TPS6521855: start up time for DCDC, LDO, LS

Hi Kei,

We are currently experiencing high support volumes. I'll provide an update within the next 2 business days.

Hi Kei,

We have an evaluation module for this PMIC family located here: TPS65218EVM-100

This device can be programmed to match the voltage outputs and sequencing of the TPS6521855. If you are using the TPS6521855 with the AM64x processor, then know that the PMIC is specifically designed to work with the processors power needs and timings. However, you can directly measure the waveforms and see if they fit your needs.

If you decide to use the TPS6521855, I suggest that you follow TI's recommended specifications in the datasheet and the application note for powering the AM64x that I will link below. Deviating from the specifications may create issues without proper testing.

Hi James,

Thank you for your suggestion.

However, we don't have the EVM.

I would like to know whether TPS6521855 has soft start function or not.

If it has, then could you tell me the rise time for the soft start?

Best Regards,

Kei Kuwahara

Hi Kei,

My pleasure. If you have any other questions let us know here on the forums!
