Part Number: UC3843 Hello,
Greetings!
We are using UC3843 IC but facing some issue in PWM generating
PWM always having maximum duty cycle. So heavy current in the input side. How to reduce the duty cycle. Please advise
Thanks & Regards …
Part Number: UC3843 Hello All,
I am studying uc3843 IC. I am trying as to how I can generate a neatly varying pwm output with a test scheme.
Can anybody here suggest such a scheme ?
Thanks in advance,

Part Number: UC3843 HI,
I rigged a circuit which given in TI WEBENCH tool ( https://webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=B7C45C111F0CE61C ). In this design for every SMD parts I found Equivalent in Through hole parts and I soldered a board…
Part Number: UC3843 I am making a non-synchronous buck converter.
Vin=400-840V
Vout=320V
Pout=4.4kW
I want to use a simple PWM IC for this circuit. UCx84x looks like a good solution, but I am confused how to calculate the compensation R and…
