@@HaseebElectronics i mean wht is the circuit diagram that u r showing in this video... 2. Can we run like blinking led for interval of some seconds. For testing purpose only. I dont have oscilloscope
yes brother. first we have to select core, then topology then flux setting by required frequency is selected then winding calculation then on that frequency you have to select dead-time (to move on CCM or DCM mode) and then select capacitor value then adjust RT value for the required frequency
@@HaseebElectronics yes sir but another issue in ur comment about CCM and DCM mode related to use 3842/3843 or 3844/3845 is when we use 3845 always work on DCM mode because it's output duty not above 50% and if we work on 3842 It's always work on CCM mode because it's output duty always more than 50% not less than 50%
@@HarpreetSingh-nl1li yes 3844 & 3845 provide 50% max because it's built in flip flop toggles and divides the oscillator frequency so the output frequency is half of the Fosc.
I have an instrument with measuring system for power supply voltages so every five six days it measure the 12 volt 10.5 volt and put device on hault ...we need to restart it several times to get it right
thank you, sir, I was waiting for this video for a long time, Sir, you are using a black color resistor, may I know why you have used the special type resistor. you could use a normal 1/4watt resistor. what is the general use of it?
thanks a lot. yes in routine we can use a commercially available resistors with tolerance. but i always to try use fix resistors with 0.1% tolerance to obtan exact results. for normal use we can use 5% tolerance resistors
hello sir I have some question it is about the GM 4pin Ignition Module my car also uses pick up coil snd E Core Ignition Coil the power source for my car is aperantly positive linear voltage regulator or relay. So that 4Pin GM Ignition Module uses the MC 3334 ic chip the exact lay out for that Ignition Module Chip can by found on Google. So can you please take a look a tell my what Im missing? I need some how to programe that thing or interupt the freqency rate some how because my car does not have retarding mechanism so its hard to start it in winter time so thats why I try to coppy this circuet or modifi it to do that task. So basicali its the question how are 555 timer ic chip frequency controled ? Or advancing or retarding frequency on demand is it posibel? If not culd the pick up by modified or ignition coil? Im not profesional electritian I surched long and culd not finde disruptive circuet or altering frequency device . So I hoppe some one has ideas how to force that thing to retard spark or pick up signal some how? Also I wuld like to know what ells culd by used to programe pick up coil signal to run 1 or more high power darlington transistors?
Thanks you for this. It pays to have a notebook nearby. So much to remember. I'm curious about the RT and CT formulas being the same for all chips or how close they are to this one. I assume that the half frequency is for push pull topography. I always love your videos. I would like to see you do a video on the L5991 (DAP002) IC like used in a Sony Playstation 2.
no it is a family of current mode smps controllers. designer can use any option. either CCM, DCM operations. basically these four ICs are used to drive unipolar magnet (flybacks, buck converters, boost converters)
Really very interesting video compliments. I would like to ask you since you explained how to calculate the frequency, could you make a video of how to calculate the inductance as a function of the frequency generated by the PWM control? A thousand thanks
Thank you very much a lot for your great efforts. I've tried to test some of theses IC, and I've had errors. Can I ask the specific pins connections you used to test it, please. Thank you in advance.
First comments and view very interested video pin me dear friend
Thank you so much
Very clear explanation to a deeper involved calculation. Thanks.
You are welcome!
best regards
Sir really a good and informative video and I will again say that a person play ur video he can't stop or skip any part of ur video .
best regards and special thanks dear brother
Thank you sir your explanation really help me a lot I really appreciate.
You are most welcome

thanks sir for all videos in this series, sir i have one doubt, how is the duty cycle set to 48%, is it done through feed back? , kindly explain
Very good and useful information sir thanks for sharing this knowledge to us

Thank you so much 😀
Can you make 3S Li-ion battery charger with this
Thanks for sharing
Great video. Can you explain compensation and show some practical examples
thanks a lot
sure i will try my best to do it as soon as i can
I learned alot here, thank you for that. For UC3843 CT= 472pf, RT = 8.2k and got 444kHz using the formula is that correct?
Hello sir please discuss about ic TEA1617 IC
welcome dear. i noted it and will explain it soon
What is the minimum circuit for testing freq this ic...
it depends on the RT/CT value
@@HaseebElectronics i mean wht is the circuit diagram that u r showing in this video...
2. Can we run like blinking led for interval of some seconds. For testing purpose only. I dont have oscilloscope
Wonderful video dear friend, happy weekend!
best regards and special thanks
Semoga sukses selalu ya kak 🙏
thanks a lot for your visit
Mohon bantuannya apa bisa UC 3842 di ganti dgn memakai UC 3843 mohon jawabannya masalasih
Selamat pagi
tidak, kami tidak dapat mengganti UC3842 dengan UC3843. karena tegangan VCC dan perbedaan siklus kerja
please check this video

Sorry sir but this video is not match with actual calculation of frequency because frequency select according to flux density of core
yes brother. first we have to select core,
then topology
then flux setting by required frequency is selected
then winding calculation
then on that frequency you have to select dead-time (to move on CCM or DCM mode)
and then select capacitor value
then adjust RT value for the required frequency
@@HaseebElectronics yes sir but another issue in ur comment about CCM and DCM mode related to use 3842/3843 or 3844/3845 is when we use 3845 always work on DCM mode because it's output duty not above 50% and if we work on 3842

3842 and 3843 can be programmed in ccm by limiting the current sense feedback
