UC3843: RT/CT amplitude

Given Ding

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.

Hi,

The low-end peak is at 0.3V or so, and high-end peak is at 2.0V or so. There is no negative peak voltage. The design should only need to know the peak-to-peak about 1.7V based on the datasheet.
