- Hi,
i am Anil vishwakarma Welcome to our UA-cam channel Science innovative brain.
About This Video:
IN THIS VIDEO LECTURE I 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 3.3 V, 5.0 V, 12 V, 15 V, 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.
FEATURES
• 3.3 V, 5.0 V, 12 V, 15 V, AND ADJUSTABLE OUTPUT VERSIONS
• ADJUSTABLE VERSION OUTPUT VOLTAGE RANGE, 1.23 TO 37 V ±4% MAXIMUM OVER LINE AND LOAD CONDITIONS
• GUARANTEED 3.0 A OUTPUT CURRENT
• WIDE INPUT VOLTAGE RANGE
• REQUIRES ONLY 4 EXTERNAL COMPONENTS
• 52 KHZ FIXED FREQUENCY INTERNAL OSCILLATOR
• TTL SHUTDOWN CAPABILITY, LOW POWER STANDBY MODE
• HIGH EFFICIENCY • USES READILY AVAILABLE STANDARD INDUCTORS
• THERMAL SHUTDOWN AND CURRENT LIMIT PROTECTION
• MOISTURE SENSITIVITY LEVEL (MSL) EQUALS 1
• PB−FREE PACKAGES ARE AVAILABLE
APPLICATIONS
• SIMPLE HIGH−EFFICIENCY STEP−DOWN (BUCK) REGULATOR
• EFFICIENT PRE−REGULATOR FOR LINEAR REGULATORS
• ON−CARD SWITCHING REGULATORS
• POSITIVE TO NEGATIVE CONVERTER (BUCK−BOOST)
• NEGATIVE STEP−UP CONVERTERS
• POWER SUPPLY FOR BATTERY CHARGERS

Thank you so much for providing useful information
Thank😊❤
Very useful for related person. Thanks.
Useful video TKQ v much
Very useful informative video
Good explanation
Very nice
👏👏👏
WowSuper
Nice
👍
Sir, LM2576T
KO CHECK KARNAY KA TARIKA BHI BATAIN MULTIMETER SAY.
THANKS
Kya problem aarha hai ye bataiye pahle...
Sir kindly share the detail of input 60v to 24v output and output current 4.17A buck regulated circuit.can i use lm2576hv ic for this purpose. or suggest any out ic or circuit.thanks
Sir ji
Inductor coil gade and how many rounds
Please tell me
Take any small ferrite core and use lit wire wound some turn and measure with LCR meter.
Sir mujhe la5756 7qno regulator k bareme thoda jankari dijie mera kco me lagahai but work nehin korrahae
Sure in 2days i will upload videos for LA5756 Separately-excited Step-down
Switching Regulator
Sir aapne variable regulator ke liye btaya hi nhi Aapne fix voltage explain kiya pls variable voltage ke liye btaye
sir kindly share CC CV power supply deatils
It's updated to LM2596 series
Kya hum ise mobile charge sefly karsakta ha??
Yes but add some protection ckt
IC 7805 bi to 5v ke liya hota hai
Yes you are right LM7805 also generates 5volt but lm7805 is a linear regulator but this will not provide current up to 3 amp. Also losses are more efficiency is about 65%
Hello Sir ! Kya yeh IC ke use se apan 240V from charging plug ko desired dc mein convert kr skte hai kya ? Jaise ki opamp ko 15 V, baki IC ko reference voltage, etc. through 240V se de skte hai kya first by converting AC to DC ? Ya phir alternate option kya ho skta hai ?
Plz reply sir🙏 It is very very much needed for me
Nhi de sakte hai 240v direct to this ic. Aap ek step down Transformers use karke diode ki help se rectified kar lijiye aur capacitor lga k filter dc bana lijiye fir is ic se aap regulated dc bana sakte hai wo bhi lo voltage ka jo kosis ic ya opamp ko chahiye
Bhai sub ic78×× maximum one amp current out put pe deta hai . Apne bola in put me jitna current dega utna hi current out put pe milega . Kya eie sahi hai . Data sheet dekha bhai sub.
Sir VFD ka full schematic mil jayega kya ? ABB ACS 550 ka ya kisi ka. I am Redy to pay for this.
I will check and tell you join me on telegram
t.me/sunsemoon
TL2575 input and output calculation formula kay hai
Which version you are using. Adjustable or fixed type.
Hi check my this video
TL2575HV high voltage switching regulator
Ye on off karsakte hii ??
Yes ON OFF kar sakte hai jaise maine video me bataya hai aapko.
sir i have made a multism diagram of your design it's working i mean but the multimeter slowly approach to desird voltage in 10 seconds is there any error
Do you have model of regulator in multisim? Delay may be due to computer processor speed
@@scienceinnovativebrain sir I have multism diagram but when I simulate the diagram it's output start from 1 volt and then in 8 second it get fixed on 5 volt
You can share the file i can check. Join telegram link on home page
Sir
Please show us power regulator circuit with this circuit.
Sir what type of power regulator circuit this can handel it self 3 amp current pls explain little bit more ur requirement
Hi what is the difference between LM2576 AND LM2596
Switching frequency are mainly different
Hello Sir, I just want to know the use of inductor here.
Inductor is use as filter L and C make filter to reduce the ripple in output voltage. (ac parts in DC)
@@scienceinnovativebrain In Adjustable version what is the role of inductor?how desired output is acheived? Actual process I want how simply putitng Volatge divider is not what we get output what actual process carried out inside?
Aslo use of Schottky diode,it is connected in reverse direction across output so when it is came in picture?in my circuit I have used Smd B1100 diode
It is used to not allow the back current in side ic due to inductors back emf . As per your application you can use diode current rating. But it should be fast recovery diode.
Working chodke sab batadia
IC 741 complete bta dijiye frequency response,cmrr,slew rate plz 🥺🥺🥺🥺🥺🥺😢
Input supply mein kitna bhi current ho tab bhi 3A milega??
Agar input mein 1A hoga to output mein phir bhi 3A milega?
Yes melega but input voltage output voltage se jayada hona chahiye.
@@scienceinnovativebrain ok.. then we will rock.
