Very very informative vedeo . So many ics are in Chinese circuits which has no nos. Or datasheet, which is big problem to repair the circuit. This is very very helpful vedeo for this. Pls share the proper calculation of output capacitor mathod Or formula also. God bless you.

Nice 👍
Kya aap neckband circuit ki ok information de skte hai kya

[guljan]

Dear Sir I have watch your videos it was so good in SMPS repair
I have adapter in PWM IC in VCC voltage low power came instead of 18V or 21V 7V come in VCC pin can you guide

[afifthbe]

i hope someday you could explaining about fast charging output concept and example actually 😊😊

thank

Hello thanks for all those interesting lessons. I have two questions... FIRST, If we have current sensor on pin 4 why we need voltage divider for pin number 3? Second does chargers switching with out load? Thank you

[ZSadeghi]

hi. I don't understand what is this winding in the left of paper and what it done ????

[giltoo]

Please tell me when we change samsung led tv orignal tv backlight, we use copyback lights not orignal then the picture of led tv good or not sry for my English 😀

Could u please do make a circuit for variable battery charger.. 12v, 24v - 72v lithium batteries, which have different cut off voltages. . so need a potentiometer for cut off voltage set ., and circuit could support upto 20 ampere current. . current adjuster can adjust from boost convertor input supply .. I am finding everywhere but not getting anywhere. Plz do make it..
