Hi Peter,Thank you very much for your reply. Now, my question is that, in order to use STUSB4710, should I use another buck converter (like ST1S14) at the output of EPC2152(will it make sense)? Please suggest a solution for this as I cannot avoid EPC...

Hi Peter,Thank you very much for the reply.In my design, I am using EPC2152 as buck converter which converts 48V input to 20V.This buck converter doesn't have feedback pin. So, in order to use STUSB4710 as USB PD, should I use ST1S14 after EPC2152? O...

Hi Peter,Thank you very much for your reply.However, if your DCDC has no feedback pin, it can only be a fixed voltage regulator that cannot be set to other voltages. In this case you should choose an adjustable one.Can you please explain your answer ...

Please find the design of DC-DC converter EPC2152. As per this diagram HRTIM_CHA1 should be connected to HSIN and HRTIM_CHA2 should be connected to LSIN. Please advise me on using other HRTIMER signals.

Thanks for your reply. I have gone through AN4539.I am using HRTIM to provide PWM signals for DC-DC converter EPC2152. Which signals of HRTIM I should use for the same? Currently, I am using HRTIM_CHA1, HRTIM_CHA2. Should I use any other signals like...

Can I use STUSB4710 without using ST1S14? I am already using another DC-DC converter to provide voltage, but there is no feedback pin for the same. So, is it compulsory that I should use ST1S14?

I am designing hardware using STM32H7. I would like to connect three power monitor devices to SPI4 of MCU as slave devices, but SPI4 has only one NSS(slave select) pin. How should I connect these multi slave devices to SPI4 of MCU?

I am designing hardware using STM32H7 and I would like to implement HRTIM to provide PWM signal for DC-DC converter. Please provide me the reference schematic that uses HRTIM.
