Note:

1. Recommended to use a capacitor with ripple current >200 mA at 100 kHz.

2. Recommended to use a high frequency, low ESR, electrolytic capacitor (<= 1.1Ω at -40 C) with at least 20% margin on voltage rating.

3. A suppressor diode (TVS) is recommended to protect the downstream application in case of converter failure and should be rated for a minimum of 1.2 times the

converter’s output voltage.
