I need to learn to build the simplest switching mode power supply. If I succeed, I hope I'll be able to work my way up and make more advanced SMPSs for other applications.
I did my research:
I've been searching everywhere for a tutorial on how to build a simple switching mode power supply, however, the tutorials and solutions I found look super complicated for me. So far I have looked at a few articles and have used the PI Expert and the Power Stage Designer Tool (from Texas Instruments) to get familiar with designing the circuit. I know how an SMPS works, but I'm afraid I need to learn how to set up the "switching" part (i.e. how to set up the IC that is in charge of controlling the MOSFETs).
Includes 5-PC-power-supplies worth of scavenged components, and I was wondering if I can actually build a smaller PCB that only outputs 12V 2A.
The simplest one is that I need to supply constant 12V to two fans, mounted on the heatsinks of two 50W LEDs, which are powered by a 100W LED driver. Linear regulation isn't a good idea for obvious reasons.
I would appreciate any help.
