EO Pin:
This pin is the output of the voltage amplifier. This pin is connected to the phase-compensation circuit of the voltage
amplifier.
SS Pin:
This pin is connected to GND or VREF via a capacitor. This pin is pulled up to the voltage on the VREF pin until PFC
operation starts. When the voltage on the PFC-ON pin has reached 0.82 V (typ.), PFC operation starts and this pin
flows 25
μ
A source current. Operation of the CAO pin is affected by that of the SS pin, the pulse width of the OUT pin
is limited, and this prevents overshooting when start up.
VCC Pin:
This pin is for the IC power supply. The IC starts up at 10.5 V (typ.), and stops at 9 V (typ.).
