If input voltage is 5V and the output is -10V, the current is not specified. Which IC can fulfill this task. The circuit should be simple and not expensive. Can anybody help me?
 

Hello,

compared to usual capacitor-switching ICs, e.g. 7660, this is more than doubling. You could chain two 7660 to achieve the result. Depends also on current requirement. The other option would be an inverting switcher with an inductor.

Regards,
Frank
