Part Number: UCC28064A
Other Parts Discussed in Thread: UCC28065, UCC28064

Dear Team,

Here is Kevin from Delta Taiwan.

The customer was using UCC28064A, and I will suggest them move to UCC28065 for better iTHD.

If this new device has other improvements please also let me know.

Please also provide GDA and GDB sink and source capability for both UCC28064/5.

Hello Kevin,

Both of these PFC controllers use the same gate driver.

Figure 12 shows the maximum drive current of 1 A and figure 13 of show the maximum drive current to be 1.8A.

The drives of both devices have an average maximum of +/- 25 mA that cannot be exceeded.

Regards,
