how to upgrade buck converter | Add this circuit voltage & Current Limit Feature to Buck Converter
0-35v adjustable voltage regulator using single Mosfet
voltage regulator | Upgrade 3 Amp Step Down Module to 50 Amps | use this circuit That's why you should add this circuit to your multimeter
Hi,
i am akash kumar yadav Welcome to my RU-vid channel
and i am showing Science and technology videos
Upgrade DC to dc bucK Converter 30 to 50 amp
IN THIS VIDEO LECTURE AM EXPALING ABOUT THE FIXED OUTPUT SWITCHING REGULATOR LM2576 WHICH CAN DILIVER 3 AMP OUTPUT CURRENT.
IN THIS DESIGN I EXPLAINED DESIGN OF 5 VOLT DC & 3 AMP LOAD CUEENT. THIS REGULATOR HAIVING INTERNAL OSSILATOR WHICH IS GENERATING 52 KHZ, TO DESIGN THE REQUIRED OUTPUT VOLTAGE AND CURRENT WE HAVE TO REQUIRED ONLY 4 EXTERNAL COMPONENT WHICH IS VERY GOOD ADVANTAGE TO REDUCE THE EXTERNAL COMPONENT AS WELL AS COMPACT POWER SUPPLY DESIGN.
THESE DEVICES ARE AVAILABLE IN FIXED OUTPUT VOLTAGES OF 3.3V 5V 12V 15V AND AN ADJUSTABLE OUTPUT VERSION
SINCE THE LM2576 CONVERTER IS A SWITCH-MODE POWER SUPPLY, ITS EFFICIENCY IS SIGNIFICANTLY HIGHER IN COMPARISON WITH POPULAR THREE-TERMINAL LINEAR REGULATORS, ESPECIALLY WITH HIGHER INPUT VOLTAGES. IN MANY CASES, THE POWER DISSIPATED IS SO LOW THAT NO HEATSINK IS REQUIRED OR ITS SIZE COULD BE REDUCED DRAMATICALLY.
