6PFC_OK
PFC preregulator output voltage monitoring/disable function. This pin senses the output voltage of
the PFC preregulator through a resistor divider and is used for protection purposes.
If the voltage on the pin exceeds 2.5 V the IC stops switching and restarts as the voltage on the pin
falls below 2.4 V. However, if at the same time the voltage of the INV pin falls below 1.66 V,
a feedback failure is assumed. In this case the device is latched off. Normal operation can be
resumed only by cycling V
CC
. bringing its value lower than 6 V before to move up to Turn-on
threshold.
If the voltage on this pin is brought below 0.23 V the IC is shut down. To restart the IC the voltage
on the pin must go above 0.27 V. 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 the 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 12 V to avoid excessive gate voltages.
10 V
CC
Supply Voltage of both the signal part of the IC and the gate driver. Sometimes a small bypass
capacitor (0.1 µF typ.) to GND might be useful to get a clean bias voltage for the signal part of the
IC.
