Hi Alvin,
I have not seen an update on this thread for the last 7 days. If there is still something open, just let me know with the new details. Best regards,

Part Number: LM5122 Other Parts Discussed in Thread: PMP7979 , Hi Team,
There is a good new that we find a new project !
SPEC : Vi : 14V / 60V
Vo : 24V / 150W
I think PMP7979 is a good Reference Design !
And I want to know how two LM5122 LOAD SHARE…
Hello Ryan,
Have a look at this reference design: https://www.ti.com/tool/PMP7979
The problem you will face in reality with LM5156 is that the external diode will have difficulties to handle the power, so it is recommended to go with a synchronous boost…
Hi CHO SR,
Thank you for considering TI solutions. Could you clarify what is exactly the issue? The Webench cannot create the design, or cannot simulate, or your customer has a hardware circuit which does not produce Vout?
Regarding your spec below, the…
Part Number: PMP21867 Other Parts Discussed in Thread: LM5122 , PMP7979 Dear Team,
Do you have reference design for -48V to 12Vout/ 10A application?
I have find PMP21867, but it's 1000W solution with 4 phase.
If you have suitable solution, please…
Hi Adrian,
Here are two other examples that might help
TIDA-01168
PMP7979
Neither is exactly what you need, but I think PMP7979 could be scaled to 4 phases to give the output you need.
TIDA-01168 is a higher power example and is bi-directional which you…
Hi Kyle,
Thanks for reaching out with your questions and for considering the LM5122 and LM5121.
Based off of the specifications provided I think these are the correct parts for the application. The power levels is pretty high (520W) I suggest using a…
Julian,
While the RDson of the FET is low the total gate charge is huge (146nC). Switching at 540kHz with the FET will not work and will cause the gate driver supply of TPS43061 to run into current limit. Not the mention the switching losses are going…
Hi NObody,
I would recommend using the LM5122. There are two major reasons.
1. Total power level is 540W and a multi-phase design will help with component selection. The LM5122 can be easily configured for 2 phase operation. Please note that for some…
