Point
Oscilloscope Measurement
Remark
G
* IC1 initial working
circuit
* It works at Initial
Voltage of 15V,
then 12V.
* It is reset to initial
state under 10V.
c) Initial Voltage of Switching Power IC
Point
Oscilloscope Measurement
Remark
H
* Protection of power
circuit
* Second side works
abnormally such as
short, etc.
* It blocks power to
protect power circuit
when Vcc is
sensed under 10V.
d) Power Protection
