{1141A} SMPS circuit without optocoupler

In this video number {1141A} SMPS circuit without optocoupler. I explained 5 volt 1 ampere cell phone charger circuit using DP1801 Quasi-Resonant PSR CC/CV PWM Power Switch. it is offline switching IC, uses auxiliary voltage as feedback. DP1801B integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Cycle-by-cycle Current Limiting (OCP), Short Load Protection (SLP), On-Chip Thermal Shutdown, VDD Clamping. DP1801B is a high performance, multi mode, highly integrated Quasi Resonant Primary Side Regulation (QR-PSR) power switch. The built-in high precision CV/CC control with high level protection features makes it suitable for offline small power converter applications

I subscribed 2 years ago and I've learned a lot. Great TEACHER, wish you all the luck and BLESSINGS.

[@k3ggaming926]

Same here, i learn mostly on his videos, if i don’t understand, i watched again and again till i get all the terms and parts principles 😂 i love it learning his videos

[@emersonmattoz3794]

im learning alot from you..god bless you and your family..

[@palwindersandhu2031]

Thanks very much dear brother for adding another detailed page in our knowledge, which reflects your experience and vast knowledge in electronics............. Regards........

Hi, as an electronic service professional, your videos are great. One request to you is to kindly upload a video of an ac to dc adapter, which gives less output voltage than the prescribed output

[@rajkhumar001]

Really awesome explanation sir. I really really enjoyed each and every seconds. ❤🎉🎉

[@HaseebElectronics]

it is my pleasure

उर्दू मे भी all video जेसे English chennal का सारा वीडियो पहेले रखा कीजिए भाई जी

[@muhammadishtiaq24]

Excellent thanks for sharing

[@susantaatha6468]

Very nice information

[@nandakumarpn-ug7zm]

nice

[@hannonadventures]

Awesome video ❤

[@nayanjagirdar8408]

Nice sir👌👍

[@omiza3416]

Mr Haseep feedback divider is connected defore rectifier diode thats mean ac is passing but not affecting the readings?

[@jcsudeshchannel8224]

Nice

[@pbelectronic9287]

Sir explain the ic all protection partially so that we understand the function of this ic.

[@MbaduMalonda-sc5dg]

sir can you please explain the details how auxilliary winding works as i dont undestand how the starting resistor will not supplying power to the chip while the starting resistor is still connected

[@nurtubeofficial1406]

Aselamualeykum hasseb i was try to biuld smps with uc3844 ic and irf840 mosfet but the vcc voltage maintain at 13v but there is no output voltage and referance voltage please can you help me out

[@MeemsPK]

Haseeb bhai mera solar mppt sy mutaliq 1 intehaai ahem sawal ha jis ka jawab lakhon log talash kar rahy hen plz os per koi solution le k aayn

[@MbaduMalonda-sc5dg]

sir please explain the voltage supplies to R1 and R2 resistor is it AC or DC ?

[@suatkaleli5075]

sa, please reissue the same with schematic diagram

[@walirahman3159]

Respact sir many charger 5 volt present but when icharge the mobile then volt gose blow 5 volt & no load & mobile not charge please send me cose of no load
