9.2.1.2.4 Operating Frequency
In the application circuit, the 350 kHz operation is selected by leaving RT and SYNC open. Connecting a 180 kΩ to 68 kΩ resistor between RT (pin 28) and analog ground can be used to set the switching frequency to 280 kHz to 700 kHz. To calculate the RT resistor, use the equation below:
Equation 4.
