USB -> 9V Stepup with short circuit protection and 500mA Input current limit

[luky315]

I'm looking for a solution to get 9V out from USB with short circuit protection and 500mA current limit to comply with the USB Specs.
I haven't a good solution yet. I found a few Stepup-converter with input current limit (LT1618) and output Voltages > 6V, but they have a problem when the output is shorted or when a big capacitive load (1000µF) is connected.
Should I add an aditional High-side Switch with short circuit protection or is there another solution?

max1896 can be a good candidate ?

The MAX1896 has soft-start, but I don't see an adjustable Current limit and Short circuit protection function.

EEVBlog has a simple soft-start vid with a couple fets somewhere

When you limit input current to a dcdc converter you limit output current by it automatically.
What are you trying to do? Limit current from huge output cap??
