Hi,

Could you please let me confirm about Control FET and Sync FET?

Datasheet doesn't explain what they are. But I guess

- Q1 Control FET -> High side FET
- Q2 Sync FET -> Low side FET

Is my understanding correct?

Regards,
Nagata.

Hello Nagata san,

Thanks for the inquiry. Your interpretation is correct. Q1 (control FET) is the high side FET and Q2 (sync FET) is the low side FET in a half bridge configuration optimized for synchronous buck converter.
