controller Charge Pump?

[eoasap]

I need more info. Why a charge pump? What is your initial voltage? What is your needed voltage? I have run a 5 volt LCD screen from a 3 volt PIC using the PWM output. There are app notes for pushing out over 200 volts using a step up coil and diodes from a lowly PIC!

I like coils for step up, but the EMI can be a problem. What is the application?

Ron, how do you run a 5V LCD from a 3V PIC using PWM ? i'd love to try it out.
