UCC5390-Q1: Rise time & Fall time testing details

Part Number: UCC5390-Q1
Other Parts Discussed in Thread: UCC5350-Q1

Hi Team,

 

I am looking for pratical test data information for Pulse rise time (tr) & Pulse fall time (tf) with Miller clamp option. As it was mentioned in datasheet w.r.t Capacitive load we have, but i am also looking w.r.t different switching frequcies. Do we have that information?

 - Can we expect lower rise/fall time than mentioned values?

 - Do we have better IC with rise/fall time in same series with single supply output for 10A preferred?

    Hi Vivek,

    The rise and fall times should be unaffected by switching frequency. In order to decrease the rise/fall times, you can reduce the load capacitance as well as the gate resistor, and this will allow the output to rise/fall faster.

    We currently do not offer any single channel isolated gate drivers similar to UCC53x0 with faster rise times. Based on your requirements and the rise/fall times table, it looks like UCC5350-Q1 may be the best fit for your needs, since it is able to achieve up to 10A peak source/sink current.

    Best regards,

    Will
