Hello,

the data sheet contains a formula for calculating RSPSP. It is also mentioned that the resistance value is normally 20 kOhm.

For an application with an input voltage of 13 V, an output voltage of 3.3 V, a switching frequency of 460 kHz and an inductance of 3.3 uH, I get a resistance value of 70 kOhm.

Is the calculation correct? What is the best choice for my application.

Best regards, Alexander
