TPS54394 Using by connect two output line

Other Parts Discussed in Thread: TPS54394

Hi

My customer is using TPS54394.
He would like to use by connecting output line (VO1 and VO2) of TPS54394.
His situation is "Vin=12 -> Vout=1.2V, Iout(max)=4A".

He thinks that output which is connected two output of TPS54394 can supply until 6A(3A + 3A).
Can TPS54394 use by connecting VO1 and VO2?

Best reggards

    I would not recommend that.  There is no provision for current sharing and these devices are not designed or intended to be operated with the outputs in parallel.  You certainly can set both outputs to 1.2 V, split the load so that some of the circuit operates from Vout1 and some operates from Vout2.  Just don't tie the two outputs together.
