Hi TI team
I design the buck push-pull converter @ 400kHz. (PWM SWITCHING)
I'd like to select an optocoupler to isolate the feedback signal.
Do you have any advice?
Thanks

Hi
The HS817B is a good choice.
Data sheet located here.

Hi John
The Cut-off frequency may be too low.
110kHz
How do you think?
Thanks
Hi,
Your switching frequency is 400kHz so you should expect to achieve a loop bandwidth of 20kHz to 40kHz.
This is a achievable with the device I suggested.
