I started designing with WeBench a buck converter using the LM5164QDDARQ1. I changed some values to reducde the part diversity in my overall deisgn (See WebenchDesign and Implemented design). With RRON being 47kOhm 1% 100ppm I would expect a switching frequency of Vout*2500/RRON = 5*2500/47 = 263.3kHz ... 268.64kHz if I take into consideration the 1% tolerance of the resistor. However, I measured frequencies between 288kHz and 337kHz depending on the line and load conditions. I have attached all measurements (CH1: TP315, CH2: TP320). Does someone have an idea why there is such a discrepance between the designed frequency and the measured one ?
