Doc ID 16202 Rev 1
6PFC_OK
PFC pre-regulator output voltage monitoring/disable function. This pin senses the output
voltage of the PFC pre-regulator through a resistor divider and is used for protection purposes.
If the voltage on the pin exceeds 2.5V the IC stops switching and restarts as the voltage on the
pin falls below 2.4V. However, if the voltage of the INV pin falls 40 mV below that of the pin
PFC_OK, a feedback failure is assumed. In this case the device is latched off. Normal operation
can be resumed only by cycling Vcc. bringing its value lower than 6V before to move up to Turn-
on threshold.
If the voltage on this pin is brought below 0.23V the IC is shut down. To restart the IC the
voltage on the pin must go above 0.27V. This can be used as a remote on/off control input.
7ZCD
Boost inductor’s demagnetization sensing input for transition-mode operation. A negative-going
edge triggers MOSFET’s turn-on.
8
GND
Ground. Current return for both the signal part of the IC and the gate driver.
9GD
Gate driver output. The totem pole output stage is able to drive power MOSFET’s and IGBT’s
with a peak current of 600 mA source and 800 mA sink. The high-level voltage of this pin is
clamped at about 12V to avoid excessive gate voltages.
10
Vcc
Supply Voltage of both the signal part of the IC and the gate driver. Sometimes a small bypass
capacitor (0.1 F typ.) to GND might be useful to get a clean bias voltage for the signal part of
the IC.
