JAJSE92B November 2017 – April 2018 TPSM84824
PRODUCTION DATA.
The switching frequency range of the TPSM84824 is 200 kHz to 1.6 MHz. The switching frequency can easily be set by connecting a resistor (RRT) between the RT pin and AGND. Use Equation 2 to calculate the RRT value for a desired frequency or simply select from Table 2.
The switching frequency must be selected based on the output voltage setting of the device and the operating input voltage. See Table 2 for the allowable output voltage range for a given switching frequency.
