Part Number: UCC256301

Hello.

I have a question about UCC256301.
For details, please see the attached document.

Thank you.

  • Hi Masazumi-san,

    Thanks for your interest in UCC256301. Increasing the capacitance of the BLK pin is ok. You might a small delay between PFC bus reaching start or stop and the device starting up or shutting down due to the larger capacitance but this effect should be minor.

    Best Regards,
