Voltage Feedback Input
This pin is an input for error amplifier
to feedback the voltage from the
converter output. Have the
overvoltage detect circuit to cut off
the drive out when the voltage is
over 8% from setting value.
Error Amplifier Output/Compensation
This pin is an error amplifier output.
Can do phase compensation or gain
adjustment by this pin.
Multiplier Input
Monitor the AC off line voltage using
this input.
Current Sense Input
Control the output voltage by sensing
the overcurrent at each cycle. This
pin connects the RC filter and 1.5 V
clamp diode.
