PRODUCTION DATA
Equation 20 is used to calculate the value of RON required to achieve the desired switching frequency.
where
For VOUT1 of 10 V and fSW of 750 kHz, the calculated value of RON is 148 kΩ. A lower value of 130 kΩ is selected for this design to allow for second order effects at high switching frequency that are not included in Equation 1.
