Bypass Capacitor Notes:

1. Input capacitor CIN is typically chosen based on the ripple current requirements. COUT is typically selected based on both

current ripple rating and ESR requirement. See AN-6006 for these calculations.

2. C7, C12, and C15 selection is largely determined by ESR and load transient response requirements. In each case, the

number of capacitors required depends on the capacitor technology chosen. Oscons can meet the requirements with less

space, but higher cost, than using low-ESR electrolytics.
