PFC ICOMP (Current Loop Compensation)
Low pass filter and compensation of the current control
loop. The capacitor which is connected at this pin
integrates the output current of OTA2 and averages the
current sense signal.
PFC VSENSE (Voltage Sense/Feedback)
The output bus voltage is sensed at this pin via a
resistive divider. The reference voltage for this pin is
3V.
PFC OVP (Overvoltage Sense Input)
The output bus overvoltage is sensed at this pin via a
resistive divider. The reference voltage for this pin is
3V.
PFC VCOMP (Voltage Loop Compensation)
This pin provides the compensation of the output
voltage loop with a compensation network to ground
(see Figure 2). This also gives the soft start function
which controls an increasing AC input current during
start-up.
GND (Ground)
The GND pin is the ground of the controller.
PFC OUT (PFC Gate Output)
This pin is the output of the internal driver stage, which
has a capability of 1.5A source and 2.0A sink current.
Its gate drive voltage is clamped at 15V (typically).
VCC (Power Supply)
The VCC pin is the positive supply of the IC and should
be connected to an external auxiliary supply. The
operating range is between 11V and 26V. The turn-on
threshold is at 12V and under voltage occurs at 11V.
There is no internal clamp for a limitation of the power
supply.
PWM OUT (PWM Gate Output)
This pin is the output of the internal driver stage, which
has a capability of 1.5A source and 2.0A sink current.
Its gate drive voltage is clamped at 15V (typically).
