I'm trying to design a flyback DC-DC converter which can provide up to 24V from a normal 12V,40Ah lead-acid battery that every car has. It can be used to run radios, small lights, relays, horns and other 24V accessories(multiple output) from a 12V vehicle.
I have done research about flyback topology, but both modes(discontinuous mode and co

I am searching for a 220VAC to +5VDC converter / regulator chipset.
Can someone suggest of other chip that provides the the given conversion. I've seen one from MAXIM (MAX610, 611, 612), it is a chipset that directly converts 110/220VAC to a regulated +5VDC (or even variable 0 to 17VDC) but I still need other options.

There are two methods for doin this
-- invert 12vdc to 12VAC then use a step up transformer
-- use a converter to raise the voltage upto 300VDC then invert
which one you want to use
