Hi John,
We have changed the RC values to 1/10 of the switching frequency. The waveform is attached.
The result shows a lot of Pulses, Let us know how to remove this and what is the solution for the same.

Part Number: UCC28740 Other Parts Discussed in Thread: UC3901 hello
we have a related question:
We want to use the UC3901 with the Ucc28740 How to calculate the RC network going into "COMP"
thanks again for your support.

Part Number: TMS320F28379D Other Parts Discussed in Thread: UC3901 In order to provide max benefit offered by Delfino control laws, how would one derive isolated output voltage for feeding back to the MCU to the appropriate ADC inputs? Traditional methods…
Part Number: UC1901 Other Parts Discussed in Thread: UC1843 Team,
The idea is to use UC1843 as PWM controller and UCx901 for feedback using a transformer:
-Do we have some more precise information to dimension/choose the transformer? Page 4 gives…
Other Parts Discussed in Thread: UC3901 , LM3524D Is there a simple PWM chip where I can put a voltage in and get a pulse width modulated signal out without needing too many other periferals (something like the UC3901, but PWM instead of AM)?
Hello Harel,
Yes, you will see a voltage ramp in CT when you connect 5V to RT. These two app notes have the best information on GPPWM SYNC. Even though the devices mentioned are not the UCC2806, the CT pin behaviors will be similar. In particular, pages…
Part Number: UC2842 Other Parts Discussed in Thread: UC2706 Dear team,
I am designing a push-Pull converter using UC2842 and UC2706 with reference to U-101 200KHz Current-Mode Converter provides 500W.
Can I get the simulation model for the power supply…
