what a great thread
i spent the whole last week googling and reading books abut smps trying to understand it.
my project is an smps 220v AC input and 5v ,5A DC output(if it worked well i will try to inhance it to give 10A).
the schematic in http://www.nxp.com/acrobat_download2...ets/UC3842.pdf on page 7 is very useful but i could not understand all the circuit
can any one please explain the operation of the circuit
i want to modify it to accept 220V input
