Hi everybody, I`m in process in designing buck regulator, nothing special, just simple CC/CV regulator. These are the specs i have in mind: Input voltage: 25-35 VDC (Powered from 24V 500VA torodial transformer) Output voltage: 0,1,2V to 25-30V Output current: 0-10 or 15A I was thinking of...

Hello everybody, after i was offline for quite a long time i decided to build flyback SMPS for my battery charger. Here is some specs i want to achieve: Input voltage: 230V AC (+/-10%) (about 325V DC) Output power: 100W Output voltage: 30V DC (adjustable from 20 to 30V if nessesery) Output...

Hi, 2 months ago I started designing my own SMPS based on Texas Instruments UCC3808 Current-mode PWM controller. It's one of the rare PWM controllers (current-mode ones) that have overcurrent protection. Topology i used is Push-Pull with IRFZ44N Power MOSFET's Schematics is in attachment. It's...
