1. Schematic
The delay time for overload protection is designed to be about 25ms with C105 (22nF). OLP time between 25ms
(22nF) and 50ms (43nF) is recommended.
The SMD-type capacitor (C106) must be placed as close as possible to the V
abrupt pulsating noises and to improve ESD and surge immunity. Capacitance between 100nF and 220nF is
recommended.
