Recommended Component Parameters in Typical Applications

Table 5 lists the recommended inductance (L

voltages. The inductance is determined by assuming that the ripple current is 35% of load current I

parameters are calculated by assuming a 22mF low ESR ceramic output capacitor and a loop gain crossover frequency

of F
