PRODUCTION DATA
The RT resistor sets the switching frequency of the converter. See Section 8.3.5 for more details. A resistor value of 40.2 kΩ corresponds to 400 kHz. The pin is also configured to set the switching frequency at 400 kHz when the RT pin is connected to VCC. Connecting the RT pin to VCC allows you to save cost and space, but placing a 40.2-k resistor allows for more flexibility if a different frequency is desired at a later time.
