LM5050-1: The current share for redundant power reference design

Part Number: LM5050-1
Other Parts Discussed in Thread: LM7480-Q1

Hi,

Does TI have the redundant reference design with the current-share?

I can't find the reference design on the TI website, If there has any reference design, please help to provide it, thank you.

Hi Rock,

Do you want to achieve equal load sharing of 2 parallel LM5050 or Priority Power Muxing of Primary and Secondary Power supplies ?

Hi Praveen,

Thanks for your quick reply,

For redundant power, I think the customer needs the equal load sharing of 2 parallel LM5050, but could you share both two applications for me?

I will share with my customer which applications they need, thanks.

Regards

Rock

Hi Rock,

Right now we do not have ideal diode controllers which can support equal Load sharing from 2 power supplies.

We can support Priority Power Muxing using Ideal Diode controllers using LM7480-Q1.

I would recommend you to have a look at 'Design # 6: Reverse Battery Protection With Priority Power MUXing' section of Six System Architectures With Robust Reverse Battery Protection Using an Ideal Diode Controller App note to understand how to achieve Priority Power Muxing.
