Part Number: UCC28180
Other Parts Discussed in Thread: UCC28070

Hi Team,

We’d like to design a PFC using the UCC28180 of TI.

The specifications of input AC voltage is 90V to 260V.

The specification of output voltage is 380V and power is 2.5KW.

We’d like to control two PFC blocks with one PWM IC.

Could you please check whether the attached circuit can be applied.

Regards

Hi Cho li,

I do not recommend to use one UCC280180 to controll two boost PFCs. that is becuase you do not have any current balance controller here, and only one phase of current and voltage can be controlled,in this way, the slaver PFC will influence the master PFC.

I suggest using UCC28070 to realise the schematic.
