DC-DC boost chip?

[GSR]

I have a small system which generate electric power (DC current). I want to store the energy, so I am looking for chip that can boost up the output voltage from the system (0.2V - 5V) to 10V DC. Any chip can do that?

How about a good ol' fashioned opamp?

Yes or if the output impeadance of the widget is high then an instrumentaion amp.

OP-Amps require Power to work. I think DC-DC converter is your best Bet. Try http://www.murata-ps.com

Good idea! I was thinking too much

Totally depends on your application. ie: is the output voltage higher than the input voltage? What's the current requirements? etc.

Output is higher than the input in my case

Current, ...... at much as possible because for energy storage

I am thinking that opamp may require power input, but the power consumption should be small
