Cry_Wolf said:how about using voltage doubler circuits
hellenic said:Hi.
I need to find a schematic 12V to 48V 4 Ampere DC to DC Converter
Someone told me that i can do that with a UC3843!
The think is that i can't find a schematic! (Or don't know how... Because i am new to electronics)
Can anyone help me?
ericgibbs said:hi,
A quick look at the UC3843 datasheet says: Vmax=30v and Imax =1amp.
Nigel Goodwin said:Not a problem, the input voltage is less than that, and the chip is only a driver - the chip is the least of his design worries!.
ericgibbs said:Had look for any design data on the web, no success, its NOT recommended for new designs.
I appreciate its just a PW driver, but the OP has been told that he can use the device, he can,
BUT it requires additional power transistors and supporting circuitry and a design.
Nigel Goodwin said:As does any design he chooses to make! - it's not really a trivial task - the obvious (and critical) part being the transformer or inductor (depending on design type).
