FUNCTIONAL BLOCK DIAGRAM

Notes)

• This application circuit is an example. The operation of mass production set is not guaranteed.

You should perform enough evaluation and verification on the design of mass production set.

You are fully responsible for the incorporation of the above application circuit and information

in the design of your equipment.

• This block diagram is for explaining functions. Part of the block diagram may be omitted, or it may be simplified.
