According to the TPS650942 datasheet, the switching frequency of SW1 is 1MHZ ,
may i know 1Mhz have any tolerance,
I use short pin for probe to measure, The current amount of switching frequency of about 715KHZ.

Qiong,
The BUCK controllers use the DCAP2 design, which can have some variation in switching frequency with changes in output voltage and input voltage. Although the typical switching frequency is 1 MHz, we expect the switching frequency to range between 0.7MHz and 1.4MHz.
