7PFC_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 2.5 V the IC stops switching and restarts as the voltage on the
pin falls below 2.4 V. However, if the voltage of the pin INV falls 40 mV below that one of the pin
PFC_OK, a feedback failure is assumed. In this case the device is latched off and the
PWM_LATCH (8) pin is asserted high. 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 0.23 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.
8PWM_LATCH
Output pin for fault signaling. During normal operation this pin features high impedance. If a
feedback failure is detected (PFC_OK > 2.5 V and INV+40 mV < PFC_OK) the pin is asserted
high. Normally, this pin is used to stop the operation of the dc-dc converter supplied by the PFC
pre-regulator by invoking a latched disable of its PWM controller. If not used, the pin is left
floating.
9HVS
High-voltage start-up. The pin, able to withstand 700 V, is to be tied directly to the rectified
mains voltage. A 1 mA internal current source charges the capacitor connected between pin
Vcc (16) and pin GND (14) until the voltage on the pin Vcc reaches the start-up threshold, then
it is shut down. Normally, the generator is re-enabled when the Vcc voltage falls below 6 V to
ensure a low power throughput during short circuit. Otherwise, when a latched protection is
tripped the generator is re-enabled as Vcc reaches the UVLO threshold to keep the latch
supplied.
10
N.C.
Not internally connected. Provision for clearance on the PCB to meet safety requirements.
11
PWM_STOP
Output pin for fault signaling. During normal operation this pin features high impedance. If the
IC is disabled by a voltage below 0.8 V on pin RUN (12) the voltage on the pin is pulled to
ground. Normally, this pin is used to temporarily stop the operation of the dc-dc converter
supplied by the PFC pre-regulator by disabling its PWM controller. A typical usage of this
function is brownout protection in systems where the PFC pre-regulator is the master stage. If
not used, the pin is left floating.
12
RUN
Remote ON/OFF control. A voltage below 0.8 V shuts down (not latched) the IC and brings its
consumption to a considerably lower level. PWM_STOP is asserted low. The IC restarts as the
voltage at the pin goes above 0.88V. Connect this pin to pin VFF (5) either directly or through a
resistor divider to use this function as brownout (AC mains undervoltage) protection.
13
ZCD
Boost inductor’s demagnetization sensing input for transition-mode operation. A negative-going
edge triggers MOSFET’s turn-on.
14
GND
Ground. Current return for both the signal part of the IC and the gate driver.
15
GD
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 12 V to avoid excessive gate voltages.
16
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.
