Part Number: CDCUN1208LP

I need to know if there is any constraints on power down

it is clear from the datasheet that i need to start up on strict manor but nothing about the power down.

my system runs from

VDD CORE - 3.3V

VDDO1,2,3,4 voltage - 1.8V

Thanks

Hi Shaii,

I have reached out to designer to take a look at the output stage supply. Once I confirm how it looks like, I will get back with to you with feedback by tomorrow.

Best,

Asim

Hi Shaii,

I have checked internally and chip designer recommended that its better to have the VCC and VCCO power off at the same time or make sure VCC is present when powering off VCCO.

Best,
