FAN7529
Critical Conduction Mode PFC Controller
Features
Description
„ Low Total Harmonic Distortion (THD)
The FAN7529 is an active power factor correction (PFC)
controller for boost PFC applications that operates in critical conduction mode (CRM). It uses the voltage mode
PWM that compares an internal ramp signal with the
error amplifier output to generate MOSFET turn-off signal. Because the voltage-mode CRM PFC controller does
not need rectified AC line voltage information, it saves the
power loss of the input voltage sensing network necessary for the current-mode CRM PFC controller.
„ Precise Adjustable Output Over-Voltage Protection
„ Open-Feedback Protection and Disable Function
„ Zero Current Detector
„ 150µs Internal Start-up Timer
„ MOSFET Over-Current Protection
„ Under-Voltage Lockout with 3.5V Hysteresis
„ Low Start-up (40µA) and Operating Current (1.5mA)
„ Totem Pole Output with High State Clamp
FAN7529 provides many protection functions, such as
over-voltage protection, open-feedback protection, overcurrent protection, and under-voltage lockout protection.
The FAN7529 can be disabled if the INV pin voltage is
lower than 0.45V and the operating current decreases to
65µA. Using a new variable on-time control method,
THD is lower than the conventional CRM boost PFC ICs.

Pin Definitions
Pin #
Name
Description
1
INV
This pin is the inverting input of the error amplifier. The output voltage of the boost PFC
converter should be resistively divided to 2.5V.
2
COMP
This pin is the output of the transconductance error amplifier. Components for output
voltage compensation should be connected between this pin and GND.
3
MOT
This pin is used to set the slope of the internal ramp. The voltage of this pin is maintained at 2.9V. If a resistor is connected between this pin and GND, current flows out of
the pin and the slope of the internal ramp is proportional to this current.
4
CS
This pin is the input of the over-current protection comparator. The MOSFET current is
sensed using a sensing resistor and the resulting voltage is applied to this pin. An
internal RC filter is included to filter switching noise.
5
ZCD
This pin is the input of the zero current detection block. If the voltage of this pin goes
higher than 1.5V, then goes lower than 1.4V, the MOSFET is turned on.
6
GND
This pin is used for the ground potential of all the pins. For proper operation, the signal
ground and the power ground should be separated.
7
OUT
This pin is the gate drive output. The peak sourcing and sinking current levels are
+500mA and -800mA respectively. For proper operation, the stray inductance in the
gate driving path must be minimized.
8
VCC
This pin is the IC supply pin. IC current and MOSFET drive current are supplied using
this pin.

FAN7529 Critical Conduction Mode PFC Controller
Typical Characteristics (Continued)
1. Error Amplifier Block
below 1.4V. If the voltage goes below 1.4V, the zero current detector turns on the MOSFET. The ZCD pin is protected internally by two clamps, 6.7V-high clamp and
0.65V-low clamp. The 150µs timer generates a MOSFET
turn-on signal if the drive output has been low for more
than 150µs from the falling edge of the drive output.
The error amplifier block consists of a transconductance
amplifier, output OVP comparator, and disable comparator. For the output voltage control, a transconductance
amplifier is used instead of the conventional voltage
amplifier. The transconductance amplifier (voltage controlled current source) aids the implementation of OVP
and disable function. The output current of the amplifier
changes according to the voltage difference of the inverting and non-inverting input of the amplifier. The output
voltage of the amplifier is compared with the internal
ramp signal to generate the switch turn-off signal. The
OVP comparator shuts down the output drive block when
the voltage of the INV pin is higher than 2.675V and
there is 0.175V hysteresis. The disable comparator disables the operation of the FAN7529 when the voltage of
the inverting input is lower than 0.45V and there is
100mV hysteresis. An external small signal MOSFET
can be used to disable the IC, as shown in Figure 33.
The IC operating current decreases below 65µA to
reduce power consumption if the IC is disabled.

3. Sawtooth Generator Block
2.675V
The output of the error amplifier and the output of the
sawtooth generator are compared to determine the
MOSFET turn-off instance. The slope of the sawtooth is
determined by an external resistor connected to the
MOT pin. The voltage of the MOT pin is 2.9V and the
slope is proportional to the current flowing out of the
MOT pin. The internal ramp signal has a 1V offset; therefore, the drive output is shut down if the voltage of the
COMP pin is lower than 1V. The MOSFET on-time is
maximum when the COMP pin voltage is 5V. According
to the slope of the internal ramp, the maximum on-time
can be programmed. The necessary maximum on-time
depends on the boost inductor, lowest AC line voltage,
and maximum output power. The resistor value should

Output
The zero current detector (ZCD) generates the turn-on
signal of the MOSFET when the boost inductor current
reaches zero using an auxiliary winding coupled with the
inductor. If the voltage of the ZCD pin goes higher than
1.5V, the ZCD comparator waits until the voltage goes

Applications Information
5. Switch Drive Block
The MOSFET current is sensed using an external sensing resistor for the over-current protection. If the CS pin
voltage is higher than 0.8V, the over-current protection
comparator generates a protection signal. An internal RC
filter is included to filter switching noise.
The FAN7529 contains a single totem-pole output stage
designed for direct drive of the power MOSFET. The
drive output is capable of up to +500/-800mA peak current with a typical rise and fall time of 50ns with 1nF load.
The output voltage is clamped to 13V to protect the
MOSFET gate if the VCC voltage is higher than 13V.

6. Under-Voltage Lockout Block
If the VCC voltage reaches 12V, the IC’s internal blocks
are enabled and start operation. If the VCC voltage drops
below 8.5V, most of the internal blocks are disabled to
reduce the operating current. VCC voltage should be
higher than 8.5V under normal conditions.
