PowerShot A200 with 5 volts supply?

[Private]

I want to use my PowerShot A200 with
5V power supply on place of original 3.3V.

Idea is short flash recharge time.

Is somebody trying to use camera in this way?

This is a list of chips inside:

Power supply - Sanyo LA5679
CCD control - Sharp LR36685
TFT control - Sony CXA3572R
ASIC - NEC D82434S1023 FH4-1368
ASIC - Fujitsu CK4-0377 E053
TFT display - Sony AM309-3 A CCD0132Z05838
Input power supply filter: 47µF/6V

I still try to find datasheet for Sanyo LA5679.
