Description
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. 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 65A. Using a new variable on-time control method, THD is lower than the conventional CRM boost PFC ICs.

Description
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. This pin is the output of the transconductance error amplifier. Components for output voltage compensation should be connected between this pin and GND. 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. 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. 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. 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. 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. This pin is the IC supply pin. IC current and MOSFET drive current are supplied using this pin.

Applications Information
1. Error Amplifier Block
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 65A to reduce power consumption if the IC is disabled. 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 150s timer generates a MOSFET turn-on signal if the drive output has been low for more than 150s from the falling edge of the drive output.

Figure 34. Zero Current Detector Block
3. Sawtooth Generator Block
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 be designed properly.

4. Over-Current Protection 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.
5. Switch Drive Block
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.
