Hi Expert,
Our customer uses our LM51561-Q1 in a flyback application. They test GATE pin and it shows as below. They set the frequency as 100kHz. But as you can see below, the duty cycle is varying. The black square is ~38.5kHz and red square is 125kHz. Could you please help take a look and give some hint? Really appreciate!
BTW, the customer is unwilling to share their schematic. So you ever see this waveform before? Thanks.
BR,
Elec Cheng
