Hi team,

My customer is using the TPS51206 now, the structure is below. Whether the structure has additional issues? Real current is very small which is only 1A. Thanks.

Hi Frank,

TPS51206 can not be stackable.

If the actual current is only 1A, one TPS51206 is enough.

Thanks

Qian

Hi Qian,

Many thanks. What's the risks? For example, A channel will give current to B channel. Thanks.

Hi Frank,

Two TPS51206 can not share current. One device may source current while the other device may sink current, this is cause large power loss on both device.

Thanks
