Pin num.
Name
Function
9COMP
Output of the error amplifier. A compensation network is placed between this pin
and INV to achieve stability of the PFC voltage control loop and ensure high
power factor and low THD.
10
INV
Inverting input of the error amplifier. The information on the output voltage of the
PFC pre-regulator is fed into the pin through a resistor divider. Input for the
feedback disconnection comparator
11
ZCD
Boost inductor’s demagnetization sensing input for PFC transition-mode
operation. A negative-going edge triggers PFC MOSFET turn-on.
During start-up or when the voltage is not high enough to arm the internal
comparator (e.g. AC Mains peak), the PFC driver is triggered by means of an
internal starter.
12
PFCS
Input to the PFC PWM comparator. The current flowing in the PFC mosfet is
sensed by a resistor; the resulting voltage is applied to this pin and compared
with an internal sinusoidal-shaped reference, generated by the multiplier, to
determine the PFC MOSFET’ s turn-off.
A second comparison level detects abnormal currents (e.g. due to boost inductor
saturation) and, on this occurrence, shuts down and latches the IC reducing its
consumption to the start-up.
An internal LEB prevents undesired function triggering.
13
PFG
PFC gate driver output. The totem pole output stage is able to drive power
MOSFET’S with a peak current of 300mA source and 600mA sink.
14
HBCS
2-levels half-bridge current monitor for current control.
The current flowing in the HB mosfet is sensed by a resistor; the resulting
voltage is applied to this pin.
Low threshold (active during run mode): in case of thresholds crossing, the IC
reacts with self-adjusting frequency increase in order to limit the half-bridge
(lamp) current.
High threshold:
– ignition: in case of thresholds crossing during the frequency shift, the IC reacts
with self-adjusting frequency increase in order to limit the lamp voltage and
preventing operation below resonance.
– run mode: in case of thresholds crossing because of current spikes (due e. g.
to capacitive mode / cross-conduction), the L6585D latches to avoid
MOSFETs damaging,
15
GND
Ground. Current return for both the signal part of the IC and the gate driver.
16
LSD
Low side driver output: the output stage can deliver 290mA source and 480mA
sink (typ. values).
17
VCC
Supply Voltage of both the signal part of the IC and the gate driver.
Clamped with a Zener inside.
18
OUT
High Side Driver Floating Reference. This pin must be connected close to the
source of the high side power MOS.
19
HSD
High side driver output: the output stage can deliver 290mA source and 480mA
(typ. values).
20
BOOT
Bootstrapped Supply Voltage. Between this pin and VCC, the bootstrap capacitor
must be connected.
A patented integrated circuitry replaces the external bootstrap diode, by means
of a high voltage DMOS, synchronously driven with the low side power MOSFET.
