Operation description
During start-up phase, VR is closed when electrified; FB pull-up power source is closed, the start-up
current is input from power transistor to VCC through OE; OB controls the base current of power
transistor and limits the current of power transistor collector (namely, CR6203 starts the acceptance
current), accordingly, the security of the power transistor is ensured; when VCC voltage goes up to 8.8V,
the start-up phase is ended, and it comes into the normal phase.
During normal phase, VCC voltage shall keep at 4.8~9.0V, VR outputs 2.5V benchmark; FB pull-up
