Before applying input voltage, isolate the UC3843's VCC input and power it with a benchtop DC supply. Gradually raise the DC input on VCC and observe the UVLO threshold turn-on. You can check the signals at VCC, OUT, VREF, and RT/CT, verify proper VCC and expected VREF as well as PWM output at your desired frequency (set with RT/CT values).
