Hi there! Is there a way to set the maximum duty cycle of an UC3842 to 80% instead of the default of 97%. I need to design a boost...

12V; 4000W; efficiency better than 0.95 at full load.

Since it is 50% duty cycle you must measure half the voltage from the ir2153 supply voltage with a cheap multimeter, or 100% input...

Pls can someone tell me how to solve the problem my ir2153 smps produce more than 1000V from the output at least that's what multimeter...

I made a different driver board for the video and uses HF soft start and short circuit protection with current trafo and SCR. I still...

Audio smps 550 watts 700watts peak Here is an audio half bridge smps that can be altered in quite a lot of ways. This smps was...

Thanks so much bro, please remain bless

IR2153 can directly drive medium power types like (10A) IRFB740 Qg=63 nC max. or (20A) SPP20n60C3 Qg=87 nC and many others provided the...

thanks pergo waiting for your results after holidays

Thanks so much for the detailed explanation, I think the chip is a fake as you said, we in Nigeria are suffering in the hands of the...

Some fake chips refuse to start below 12v however you can make some changes to help with startup. 1, change the 10v zener to 12v 2...

Please can someone tell me which MOSFET ir2153 can drive I needed it urgently thankd

Hello Mr Silvio its a good evening in my country now, how are u thanks so much for the previous help and the explanation u gave to me. I...
