Dear team,
we use LM74670 in new design, but our MOS will be damaged.(Q10 or Q18)
please see the schematic and waveform and guide us how to resolve this issue. Thanks!
AC input: 16-24Vac
mos: MTE050N10KRV8
1. The first question is that the MOS is burned. In fact, the current peak is not so large. I want to know what other reasons may cause the mos to be abnormal.
2. The second question is whether the reverse of the current is a problem, because the EVM board has also seen it, it may be normal, right?
Many Thanks,
Jimmy
