Table 5: R_A, C_A, R_CA and R_EA Values for Various PVIN/VOUT Combinations: Best Performance vs. Smallest Solution
Size. Use the equations in Figure 10 to calculate R_B.
Note 6: Output ripple is measured at no load and nominal deviation is for a 15A load transient step.
Note 7: For compensation values of output voltage in between the specified output voltages, choose compensation values
of the lower output voltage setting.
