Note: The parts list presented above is an example of recommended parts. Although the parts are standard, actual circuit
characteristics should be carefully checked on your application before use. Be sure to allow a sufficient margin to
accommodate variations between external devices and this IC when employing the depicted circuit with other circuit
constants modified. Both static and transient characteristics should also be considered in establishing these margins.
When switching noise is significant and may affect the system, a low pass filter should be inserted between the VCC and
PVCC pins, and a schottky barrier diode or snubber established between the SW and PGND pins.
