Other Parts Discussed in Thread: UCC28782
Hello,
I created a circuit using LMG3616 as switching for active clamp of UCC28782.
A schematic diagram of the circuit is shown below.
Also, this figure is based on Figure 9-1 of the UCC28782 data sheet.
A voltage of VS13 is applied to AUX. AUX uses a 0.033uF bypass capacitor.
The IN inputs the signal from the ISO7710F OUT.
RDRV is connected to AGND with a resistor.
PAD, AGND, S are connected to the switch node of this circuit (ISO7710F GND2 node).
(Question)
In the circuit I created, LMG3616 is not switching even though AUX and IN are input normally.
It is possible that the malfunction is due to noise, but are there any other reasons why the switch cannot be switched?
First of all, is it okay to use LMG3616 for the active clamp of UCC28782?
Best regards,
