Dear team,

When the VCC1 voltage is 5V, input frequency is 12kHz, what's the current range(especially the max) through VCC1 PIN?

Thanks!

Hi Mingkang,

VCC1 of UCC5880 is almost entirely independent of switching frequency, so IQVCC1 can be used for both switching and no switching conditions. So the max current is 6.5mA.

Regards,

Daniel
