UC2901 Output Swing

Other Parts Discussed in Thread: UC1844, UC2901

Hi,

I have one doubt about UC2901 output voltage Swing. In my circuit, UC2901 drives the error amplifier in UC1844 PWM controller. The voltage divider at  error amplifier in PWM controller sets my output voltage. Hence essentially, I need the output voltage of UC2901 to be same as my input voltage to this IC. (Ideally the Gain must be 1).

Does this work if my input voltage is 5V. What is the Maximum Output swing possible from UC2901. Can it go upto +/-VIN? Or can it go only upto +/-2.8V?

Thanks
