This question already has an answer here:
I need to voltage boost my battery voltage 3V to 12V DC to power cheap RF module transmitter. The boost voltage will last until I transmit 3 or 4 bytes of serial data. Roughly 5ms time.
I read this wonderful article by olin lathrop & trying to understand it.
I need 3V to boost upto 12V. 50mA current is more than enough. Supply battery is CR123 3V Cell.
I have some questions...!
1) Where is the boosted output voltage calculation? How to calculate it?
2) What component values need to change in the attached diagram to get 12V/50mA?
