Other Parts Discussed in Thread: C2000WARE
Hello,
I am curious how the inductor current sensing amplifier was designed or what the purpose of it is?
It looks like a mixture of a differential amplifier with common/differential mode filtering.
Are there any simulations/ frequency response of the current sense amplifier? I have been trying to simulate it in PSPICE and I'm observing different behavior than I would expect.
I am trying to make another board similar to this to test the TIC2000 and want to know how I might need to modify this filter to accommodate a higher switching frequency.
Thanks,
Joseph
