Note:

1. Output filtering capacitor C2 is electrolytic capacitor, it is recommended to apply electrolytic capaci-

tor with high frequency and low resistance. For capacitance and current of capacitor please refer to

manufacture’s datasheet. Capacitor voltage reduced to at least 80%. C1 is ceramic capacitor, which

is used to filter high-frequency noise. TVS is a recommended component to protect post-circuits if

converter fails.

2.The product in the application must connect external electrolytic capacitors C2, to achieve lower

ripple noise and better dynamic load performance.

3.When the product’s output terminal is connected to high frequency switch type load, electrolytic

capacitor C2’s selection is as shown in table 2.
