Hi Zhang,

No we do not recommend this parallel operation with this control architecture as you have issues with current sharing. You may need to consider a peak current mode device for this type of operation or find another device that works for the conditions. If you want to let us know the Vin, Vout, Iout, etc. and other features that you are looking for, we can recommend alternate devices.

Thanks,

Amod
