AM4372: discrete power rails for AM4372

Part Number: AM4372
Other Parts Discussed in Thread: TIDEP0020, TLV62565, TLV62080, TLV702, TLV803, TLV62568A, TLV743P, TLV740P, TLV803E

Dear Champs,

We are trying to suggest discrete power rails for AM4372 based on below ref. design(TIDEP0020).

https://www.ti.com/tool/TIDEP0020

And, we found below analog parts were used in this ref. design.

Output Voltage

PN

Type

Current
(A)

Reference Design

3.3V

TLV62565

Buck

                 1.50

1.1V

TLV62080

Buck

                 1.20

1.5V

TLV702

LDO

                 0.30

1.8V

TLV702

LDO

                 0.30

 

TLV803

Reset IC

 

To optimize cost, we are trying to suggest below instead of above, and DDR3L will be used in our customer's system.

Could you please check if below devices can be used for AM4372 power rails?

I'm afraid the 1A current limit of TLV62568A is not enough for core voltage(1.1V) of AM4372, right?

or could you please suggest best price option for AM4372 power rails?

New Proposal
