Other Parts Discussed in Thread: UCC24612
Hi,
My customer used UCC24630 for ACF flyback and on the secondary side high side.
They found the dead time will form 2us~0.5us in High/Low AC input voltage, As a result, the current passes through the body diode of the MOSFET for too long, causing the mos to become hot.
We had to change the Rtblk from 22k to 47k but it doesn’t work. Is there any other reason for this phenomenon?
