The high side gate drive pin7 gets its power from the bootstrap capacitor. This capacitor charges itself when the lowside mosfet comes...

I've already build smps using uc3844, 43,45 and 42 but now am trying to build using ir2153 half bridge the problem I have after building...

Can someone tell me how I can use digital multimeter to test the ir2153 if it is oscillating, my smps I tried to design when I put DMM...

One other thing I am noticing is that the voltage regulation at pin 1 is all depending on the internal 15v zener inside the chip. I also...

The IR2153 is designed to power medium power mosfets, (10A) however in this circuit the 20n60 mosfets used have a a very low gate charge...

I try to built this smps but each time I power on the MOSFET blow and I use this schematic I don't know what causes it, ur help would be...

First of all if you intend to build a high current smps, then it has to be prepaired from the design stage. Type of transformer...

I mean SMPS

I have currently this week built amps using uc38xx series on Vero board it works one is 60-0-60 and the other is 17-0-17 and it work...

Yes thanks in advance I will get to you pls

Do you have a problem maybe I can help you? Regards, Silvio

Thank you very much Sylvio! The IC I use is TL494, not IR2153. I have tried with an atx transformer without rewinding and 40khz with a...

Well I also tried my software Excellent IT 7300 at this but as you can see the rated transformer power is far less the the desired...
