UCC28C44: RT-CT Dutycycle.

Shinu.V.Mathew

Part Number: UCC28C44
Other Parts Discussed in Thread: UC3844, UCC38C44

Hi Team,

One of my customer is using UCC28C44 and need to know the availability of any equation between Programmable duty cycle( ex: 30%,35%..etc) and CCT as CCT is controlling both oscillator frequency and duty cycle?

If there is no such equation customer have to do trial error to meet both frequency and duty cycle by adjusting RRT and CCT.

Can you please help on the same.

Hi Shinu.V.Mathew,

I suggest that you use the method given in UC3844 datasheet to determine the component values.

Once you have done this, just check with Figure 1 to make sure that the values obtained match UCC38C44 device.

Thanks
