Description
Variable DC to DC converter with Current Control
I Made this DC DC converter to to be used as Lab power supply. using an 12V 120W SMPS one can easily get around 100W of power i.e maximun of 30V at 3.5amps.
The Schematic
this utilizes a UC3843 SMPS I/C as a PWM generator and LM358 for current regulation stuff .this circuit is self explanatory, this design is fully modular that means you can use a powerfull mosfet along with suited inductor choke and rectifying doide for a more powerful DC DC Converter.
