I planned on using the SN6506B to drive a transformer in order to get a small amount of isolated power for a Vishay IR preamplifier . I need the isolation that the transformer provides because of the sensitivity of the Vishay IR preamp (there is a 3 amp laser driver on the same board, I want to separate that driver's ground from the preamp's ground).
It is a battery powered operation . I use a 3 volt Lithium battery.
The SN6505B is almost perfect for this application, except that I need to shut it down (which I can since it has an ENABLE pin) and wake it up quickly. The soft-start time for this chip is too long though for my application. I know all about the benefits of soft-start.
My questons:
1. Can I reduce the soft-start time for the SN6506B?
2. If not, is there another IC that is similar to the SN6505B but has much shorter (less than 500 us) soft-start time?
