Hi everyone . I need some guidance in DC/Dc converter. I have 385 Volts DC after PFC part and i want to convert it to 12V dc . I have selected UC3844 Ic for this purpose. My first question is that will it be able to do the job(I havent any other Ic available).Second that I need to know about how to select its component values as i couldnt find it on its datasheet thanks.
