Application Notes
Typical Application Circuit
The power supply has a built-in filter, which meets the requirements of general power supply applications. If a power supply system with higher requirements is needed, an external filtering network (such as an LC or π type network) can be added to the input circuit. A typical application circuit is shown in the figure.
