8.2.2.2.2 Switching Frequency Selection

Connect a 6.9kΩ resistor from RT to AGND to set a switching frequency of 2.1MHz per phase, which is designed for an output of 5V as the device establishes an inductor peak-to-peak ripple current in the range of 20% to 40% of the 6A rated output current at a nominal input voltage of 12V.
