Hi Experts,

When calculating R(CL), can we set Iout with the current limit per one channel?

Hi Uchikoshi-san,

At this moment, unfortunately no. However, you can parallel the channels. For example, if you parallel 2 channels, then the current limit for the paralleled channel will be 2 times, while the other channel remains the same current limit.

Hope this helps.

Hi Yichi,

Thank you for your answer. Please let me confirm.

The current limit is 2.5A. So if each channel current is less than 2.5A, can user support less than 10A for total?

Regarding using parallel 2 ch, can user simply connect OUT1 and OUT2 together?

That's correct understanding for both. For paralleling, there might be current imbalance between the channels. Please refer to this app note for more info: https://www.ti.com/lit/an/slva949/slva949.pdf
