hi,

I have one question for TPS456D24: how to do power-up sequencing without pm-bus control for it in default state ?

Hi user,

Can you describe your power up sequence requirements in detail?

Hi John

There're several DC/DC converters on my board, only this chip has a PMBus interface. I hope my design will get:
1, The power-up sequence of these chips is controlled by their signal pin, such as 'enable', instead of pmbus.
2, The output voltage of TPS546D24 can be slightly adjusted by CPU through the pmbus interface.

Thank you,
Gavin
