Part Number: UC3843 Hi Team,
I see there is amplitude peak to peak voltage 1.7V typical for RT/CT pin in datasheet, just want to check the max positive side and min negative side voltage on RT/CT pin. 1.7V should be Vpositive-Vnegative. Thanks.

Part Number: UC3843 Hello. I called the support center in Japan. I was told to request by email. We use UC3843 (PWM controller) for our welding machine. The UC3843 does not work, so please investigate what is wrong. Where can I send the UC3843 (actual…
Part Number: UC3843 Hi Team,
Just want to check why there is limitation on RT value and CT value selection. Is it limited by min voltage on RT/CT pin and what's the min voltage on RT/CT pin? Thanks.

Part Number: UC3843 Other Parts Discussed in Thread: UCC28C43 We're looking for the UC3843's Pspice model for simulation. However, we only find out one on ti.com that is UCC28C43. Are both identical? What's the difference?
Is this Pspice model…

Part Number: UC3843 Hey team,
Got an odd one for you here:
The datasheet calls for 2 decoupling caps, a .1, and one that is 10 times greater than the switching FET’s gate charge. The datasheet ALSO calls out for a series resistor on the Vcc pin. Does…
Part Number: UC3843 I need support about the choice of the right controller for a high power (2kW) step-down converter with adjustable output voltage. The application is DC Variac (chopper).
