Hi, i need to build a step-up converter which has an input range about 12v to 13.8v. The input needs to be step-up to 18.5/19v. The problem lies with the output current as it must be able to generate a max of 3.5A to the load.
by changing the Freq it changes the speed it can charge the caps thus changing the voltage.
well this is from what i understand i am looking into dc to dc convertors my self i want to get 12volt to 240volt with a current of 100amps
Added after 7 minutes:
it has a sync pin that you can adjust its freq to get a different voltage but as to how that sync pin works i not sure i had a quick look at the PDF but there was not much help on it from my understanding it had a coupling cap this leads me to believe that a external clock was used.
