9.2.2.2 Setting Switching Frequency
The switching frequency is set by a resistor connected between the FSW pin and the SW pin of the TPS61088-Q1. The resistor value required for a desired frequency can be calculated using Equation 5.
Equation 5. 
where
- RFREQ is the resistance connected between the FSW pin and the SW pin.
- CFREQ = 23 pF
- ƒSW is the desired switching frequency.
- tDELAY = 89 ns
- VIN is the input voltage.
- VOUT is the output voltage.
