The LM2576 series of regulators are monolithic
integrated circuits that provide all the active functions
for a step-down (buck) switching regulator, capable of
driving 3-A load with excellent line and load
regulation. These devices are available in fixed output
voltages of 3.3 V, 5 V, 12 V, 15 V, and an adjustable
output version.
Requiring a minimum number of external
components, these regulators are simple to use and
include fault protection and a fixed-frequency
oscillator.
The LM2576 series offers a high-efficiency
replacement for popular three-terminal linear
regulators. It substantially reduces the size of the
heat sink, and in some cases no heat sink is
required.
A standard series of inductors optimized for use with
the LM2576 are available from several different
manufacturers. This feature greatly simplifies the
design of switch-mode power supplies.
Other features include a ±4% tolerance on output
voltage within specified input voltages and output
load conditions, and ±10% on the oscillator
frequency. External shutdown is included, featuring
50-μA (typical) standby current. The output switch
includes cycle-by-cycle current limiting, as well as
thermal shutdown for full protection under fault
conditions.

12v se 5v capacitor 470uf volt.?? 220uf volt kitna pl capacitor ka volt bataeye …..
Ic ka price kya hai
54v dc par ye converter jal jata hai kam nhi karta hi
सर मोबाइल चार्ज वोल्टेज ज्यादा तो नही होगा और हिटसि
Please explain how have you selected values for the Caps and Inductor. The math behind it.
78xx aur 79xx LM3x7 ki video mai nay abhi upload ki hay. Check karain
Sir kay inductor lagana jaruri hey???
Inductor ka kam केया हे
68uh inductor kitna amp hoga
Thanks
Guruji aapka 68uh inductor kitna amp se kekar kitna amp Tak laga saktahu?
Can u provide me circuit for variable input viltage from 50v to 120 v dc and fixed output of 12 v or 24 volt or 36 volt any of them. Total 2000 circuits required. Contact me at jsbmatrix@gmail.com
Excellent
Nice
thanks
Praveen Sir agr source voltage ka ampere 500 Mili Ampere ho to kya yeh circuit properly work krega. Aur kya ye out put me 3 ampere dega, Please tell me sir,
Thank you.
Can we use two circuit in series to work on 120v dc input
And 2 different output
? Please answer
sir ic me Heatsink lagana he ya nahi?
sir ye ic 24 volt ka bhi aata he kya?
Can we use adjustable amp with this circuit….please tell us how to make this….. Amp adjustable..
Can i use 100uh Inductor instead of 68uh…?
sir can we use it as a power bank for mobile
nice video . the only doubt is to know if it regulates the output voltage when the input voltage decrease …. does it regulates or not ? it must be a CONVERTER NOT A REGULATOR .
but is a nice video any way thanks .
2576 hai ya 2596 .
..confused
Using 0-12 , 3amp and Rs401L diode bridge I get 21volt unloaded output . can I use it in 4440 double IC board?please reply me as soon as possible
thank you praveen
