Description
5/39
6TBO
Tracking Boost function. This pin provides a buffered VFF voltage. A resistor connected
between this pin and GND defines a current that is sunk from pin INV (pin 1). In this way,
the output voltage is changed proportionally to the mains voltage (tracking boost). If this
function is not used leave this pin open.
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 at the pin exceeds 2.5V the IC is shut down, its consumption goes
almost to the start-up level and this condition is latched. PWM_LATCH pin is asserted high.
Normal operation can be resumed only by cycling the Vcc. This function is used for
protection in case the feedback loop fails.
If the voltage on this pin is brought below 0.2V the IC is shut down and its consumption is
considerably reduced. To restart the IC the voltage on the pin must go above 0.26V. If these
functions are not needed, tie the pin to a voltage between 0.26 and 2.5 V.
8PWM_LATCH
Output pin for fault signaling. During normal operation this pin features high impedance. If
either a voltage above 2.5V at PFC_OK (pin 7) or a voltage above 1.7V on CS (pin 4) of
L6563 is detected 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 will be left floating.
9PWM_STOP
Output pin for fault signaling. During normal operation this pin features high impedance. If
the IC is disabled by a voltage below 0.5V on RUN (pin 10) the voltage at 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. If not used,
the pin will be left floating.
10
RUN
Remote ON/OFF control. A voltage below 0.52V 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 0.6V. Connect this pin to VFF (pin 5) either
directly or through a resistor divider to use this function as brownout (AC mains
undervoltage) protection, tie to INV (pin 1) if the function is not used.
11
ZCD
Boost inductor’s demagnetization sensing input for transition-mode operation. A negative-
going edge triggers MOSFET’s turn-on.
12
GND
Ground. Current return for both the signal part of the IC and the gate driver.
13
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 12V to avoid excessive gate voltages.
14
VCC
Supply Voltage of both the signal part of the IC and the gate driver.
