PRODUCTION DATA
Select a series resistor such that sufficient ripple in phase with the SW node voltage appears at the feedback node, FB. Use Equation 15 to calculate the required ripple resistance, designated RESR.
With VOUT of 5 V, VREF of 1.223 V, and ΔIL(nom) of 55 mA at the nominal input voltage of 12 V, the required RESR is 1.5 Ω. Calculate the total output voltage ripple in CCM using Equation 16.
