Part Number: PMP9431 Other Parts Discussed in Thread: LM5122 , LM5123-Q1 , PMP Tool/software: Hello TI,
I would like to use PMP9431 as a starting point for a slightly modified design. Do you by any chance have the design spreadsheet for this Reference…
Hi JH,
In this case, LM5123 might be a suitable part. https://www.ti.com/product/LM5123-Q1
This device is newer than LM5122, therefore it should have better availability and pricing.
Best regards, Niklas
Hi Haiden,
So, synchronous device is recommended.

Part Number: TIDA-020033 Other Parts Discussed in Thread: LM5123-Q1 , LM5122 Hello,
My customer is asking about power supply device in TIDA-020033
LM5123-Q1 is used for power supply of this reference design.
Are there other power supply devices…
Hi Shinichi,
Thanks for using the e2e forum.
Our parts with automotive rating, (which requires CISPR25 and IEC standards,) should have a "Q1" in their part number. If customer is interested in an automotive part, I would recommend to go with LM5123…
Hi Stefan,
Thanks for your reply.
The datasheet below explains that LM5123-Q1 can be used from a minimum voltage of 0.8V when BIAS ≥ 3.8V. Is this a typo?
For reference, the input voltage the customer wants to use is 3V.

Hi Marc
Marc Yaxley said: we can enable and also figure a way to disable the PVDD boost circuit we are including from TI's TIDA-020033 "red board" example.
I see. TIDA-020033 is not designed for your purpose. It mostly want to show the ClassH function…
