Note:The parts list presented above is an example of recommended parts. Although the parts are standard, actual circuit characteristics should be checked
on your application carefully before use. Be sure to allow sufficient margins 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 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 connected between the SW and PGND pins.
