LM20136: Can two parts be paralleled to current share?

Hello Kimberlee,

We don't recommend this type of set up. Every IC have different feedback regulation voltages which will lead to different regulated output. Those differences will be really small but can lead to one LM20136 regulating more than the other one.

It can also provide an unwanted current path to GND, knowing that the regulated voltages for each IC will be different, you can have one IC in Light load operation and the other IC with its HIGH-side MOSFET on.

I would recommend to use another part. I can help you pick the right device here.
What are the parameters of your system? Input/Output Voltage, Load?

Thank you very much!

Best Regards,

Hello Dorian,

Thanks for the reply.  

We'd like a part with the following parameters and can current share but haven't found the correct part.

VIN:  3-7V

VOUT:  Various (1.5V, 1V, 0.95V, 1.8V)

IOUT (Max):  6A.

Hello Kimberlee,

Have you considered TPS62480? TPS82480 (module version)?

Do you know why you the current share is important for your system ?

Let me know if you have further questions.

Thanks a lot!

Regards,
Dorian
