Product Number: LTC4358
Hi. I'm looking at ways to prevent reverse flow of current to a power supply. One solution I'm looking at is the LTC4358. It seems appropriate for the range of voltages I plan to use it for, from 10 to 25 volts max ideally. However, in simulation, I have an issue with its functionality with a high capacitve load.
When the input voltage suddenly drops from its max input voltage to 0, there is a reverse current spike of roughly 1 amp for a duration of a few nanoseconds, roughly 5-6 nanoseconds. The datasheet says that the diode should turn off within 500 ns, so this seems to be expected, but is there a way to prevent this sudden spike? I'm concerned that a sudden, short spike like this can damage my power supply.
