18 / 44 page ![]() 7.3.5 Switching Frequency (RT) The switching frequency range of the TLVM13630 is 200 kHz to 2.2 MHz. The switching frequency can easily be set by connecting a resistor (RRT) between the RT pin and AGND. Use Equation 5 to calculate the RRT value for a desired frequency or simply select from Table 7-4. Note that a resistor value outside of the recommended range can cause the device to shut down. This prevents unintended operation if RT pin is shorted to ground or left open. Do not apply a pulsed signal to this pin to force synchronization. The switching frequency must be selected based on the output voltage setting of the device. See Table 7-4 for RRT resistor values and the allowable output voltage range for a given switching frequency for common input voltages. (5) Table 7-4.
