Thank you for the response.

You mentioned the frequency after adjusting through the resistor. I would like to know the percentage of his spread spectrum (SSCG); is it 5%?

Hi Honggang,

Spread spectrum will spread the switching frequency of the device up to 16% above the set point of the baseline switching frequency as established by the RT resistor. Please see section 7.3.9 of the datasheet for more details surrounding this.

Thank you,

Joshua Austria
