Hi Expert,

Have a nice day!

For TPS7B7702-Q1’s dual channels, could these two be used in parallel to get higher current out?

Thanks!

Hi Leo,

We have had a similar request last week on this topic:

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1535873/tps7b7702-q1-supporting-single-output-with-tps7b7702-q1

The short answer is that, yes, you can parallel the TPS7B7702-Q1 to achieve higher output current. I have a reference design that is almost out demonstrating 2 methods of paralleling the TPS7B7702-Q1 to achieve higher output current. One method is limited to about 500mA (using ballast resistors) and another method can be scaled as high as you would like (but I show how to parallel up to 4 of these LDO's to achieve 1.2A output current). I will forward you the email I sent to Ted and I'm looking forward to your responses.

Thanks,

Stephen
