Seems like something that could be solved with a small capacitor bank. I may have to give this a try and see what I can figure out. I figure the input voltage would be somewhere around 5 volts and the expected output current would be 3.3 to 4.2 volts, but I bet a static 5 volts should be fine if the chip only checks to see if there is current.
