Other Parts Discussed in Thread: UCC28780, , UCC27712
Hi Team,
Hello, I am designing an active clamp flyback with GaN switches. I use UCC28780 as PWM Controller IC and LMG1210 for high-side low-side gate drive operation. I have a critical problem here. The supply of the UCC28780 provided from auxiliary winding of the transformer and this IC has internal starting operation but LMG1210 doesn't have this circuitry as I understand. The input voltage of the circuit is 48V and I can't directly supply LMG1210.
Do I have any chances to supply voltage to LMG1210 in this case from auxiliary winding? Or do you have any other gate suitable driver for this case?
Beat Regards,
Tom Liu
