Application of an LM22679

Other Parts Discussed in Thread: LM22679

I am looking at a new application where the LM22679 seems to be the right device and I have the following questions:

The device will be controlled from a current control circuit and the output voltage could be from 0V (short) to upper 30's, using a 40V supply.

Is the 4.7uH choke in the 3.3V sample circuit adequate?

Since the application is for a constant current source, ripple, non continuous output and other characteristics typical for power supplies are not an issue. Stability is important.

How can I parallel two Simple Switchers?

Thanks,

Joseph F. Mibelli
