@@Aviprink bhai Maine load test Kiya tha bana kr mere SMPS ne 19v 8A output diya jo ki 150W h lakin isse dual power supply nahi nikal Rahi thi or na hi higher voltage ban pa Rahi thi jaise 45-0-45 is chakkar me mere MOSFET or ic bahut kharab hue..... Mujhe koi simple or high watt ka circuit chahiye
Sir aaj kal har SMPS me pwm ic ka upyog kiya ja raha h Par kuch SMPS me ic no ko mita dieya jata h Usme kis no ke ic lagaa h patta nahee chalta Ke example uc3842 type h par usmen feedback pin 7 voltage pin 2 h Ek baat aur ek SMPS me problem h ke pin 6 par pwm Freqvancy bahut slow h Aur ye pin 7 par b pals batataa h
Video bahoot acha hai. Par koi bhee ic datasheet mai uski watt capacity aur output main kitne volt amper dega wo likha nahi hota. Khas kar ke LED Driver ke leye jo ic determind karte hai usme.
Nicely explained If no voltage appears on 8th pin after completing the circuit ,then the whole circuit collapsed,what could the cause While same circuit is working in other pcb please explain Thanking you in anticipation
Hello sir, uc3842a ki pin number 7ki voltage vary ho rahi hai jabki output voltage 12.15V constant hai. 120volt input pe 13V, 200V input pe 20V, 250V input pe 25V. Aisa kyon ho raha hoga. 12V4A SMPS me aisa nahi hai 80V input se 300V input tak 13.14 v fix hai
Agar ye ic kharab ho gai to kya UPS Battery se chalna off kar dega par AC se chelega Qyu ki mera UPS AC pe chal raha hai lekin jab bhi AC se Battery mode pe switch karta hu tas UPS off ho jata hai nahi to relay ko continuously switch karta rahta hai By the way love your informative video One like

avi taak mene uc3843 use karke koi vi buck converter ki video youtube pe nhi dekha hei or na hi koi circuit diagram , ek circuit diagram hei (experimental ) lekin wo wrong hei, mujhe plz help kare, mei aap se baat karna chhatha hu uss diagram k upar lekin yaha youtube pe photo nhi bhez sakta ! aap ka email kya hei ?
Sir circuit m kis kis pin par check kare k ic work kar rahi hai .gate pin 6par kitna volt hota hai.plz reply sir ek circuit work ni kar raha hai.i use it first time so.
1aur 2 comparater pin hai agar booster design karna hai to pin2 pe 2.5v rahega, 3 pe current sens. .9 se 1.2v tak rahega 4pe 5v 5 gnd 6 vg as vcc pin 7 vcc pin8 ref 5v
i'm working on this ic, but facing a problem at current sense pin, for one pwm cycle it works well (ramp signal is detected at it)but at next pwm cycle it stops at very start due to high noise, again at next cycle it works well but at next it stops pwm at very low duty, can to make a video on its practicle circuit for flyback converter?
About RT/CT. A Resistor is connected to Vref pin(8) and RT/CT pin(4). Then a capacitor is connected to RT/CT pin(4) and then it should be connected to ground but NO. It is connected to Isense pin(3). Why?
UC2844 vcc not stable /fluctuations observed on vcc and reference pin after replacement of capacitor its not get stable /some time its solve by replacing capacitor requesting you to make an video on this problem
Drain to source check kijiye. Use proper islolation transfarmer to power Oscilloscope. To avoid any kind of damage..use 100x probe or any kind of high voltage probe.
Bro I need help on this ic how to control the width of PWM, I could easily do it in SG 3525 ic and TL494. I tried a lot but on this UC series ics I couldn't vary width.

😃Very detailed explanation on related circuits in general and about the device in particular. Hats off to you man, You are really awesome! 🙏
Keep your support
Bhai please btao is ic ka use krke SMPS bnana h mujhe amplifier ke liye kitne watt ka bana sakte hai
Maine aaj tak 240 watt tak banaya hai , but isse high wattage ka bhi ban sakta ha

Output current ko bhi monitor Karwa sakte hai kya. To kya circuit modification Karni paregi???
Reply to do...
Uc3842 se 24V3A ka SMPS ban sakta hai ? Aur is SMPS ki input range 100-300 ho sakti hai please zarur bataiye.
Video bahoot acha hai. Par koi bhee ic datasheet mai uski watt capacity aur output main kitne volt amper dega wo likha nahi hota. Khas kar ke LED Driver ke leye jo ic determind karte hai usme.
Mosfet(switching transister) builtin hai toh toh rated power likha hoga.

Use star ground technique with decoupling capacitor close to current sense pin
@@Aviprink, i have tested it on breadboard, now i will make it on a pcb board, with star grounding.
On breadboard it will not perform well due to parasitic capacitance. Use good quality PCBs with proper grounding technique to reduce noice.
