Basic PFC application diagram
7.2.1 Regulation loop
The control loop senses the PFC output voltage via resistors R1, R2 and the feedback
input FBPFC. The frequency compensation network C1, C2 and R4 sets the response
time and stability of the loop. The voltage at pin FBPFC is regulated to V reg(FBPFC) . When
voltage on pin FBPFC is above the regulation voltage, pin COMPPFC is charged and
when voltage on pin FBPFC is lower, pin COMPPFC is discharged. Current flow through
pin COMPPFC is controlled by the PFC Operational Transconductance Amplifier (OTA)
and its transconductance g m(PFC) . The voltage on pin COMPPFC controls the PFC
on-time, t on(PFC) . So when the voltage at pin FBPFC is too high, t on(PFC) is reduced and
less energy is transferred. When voltage at pin FBPFC is too low, t on(PFC) is increased and
more energy is transferred.
The voltage on pin FBPFC is sampled at the rising edge of pin GPFC and held internally
during the leading edge blanking time t leb(FBPPC) before going to the OTA to prevent
disturbance of the regulation level due to transition effects when the PFC external power
switch is turned on
The maximum t on(PFC) is set when the voltage at pin COMPPFC is clamped to
V clamp(COMPPFC) to limit the dead time in recovering regulation after a regulation range
overshoot. The t on(PFC) time can be regulated down to zero. The moment at which the
gate is turned on is determined by pin AUXPFC. When this pin is below demagnetization
detection voltage V det(demag)AUXPFC and the low PFC off-time t off(PFC)low timer is finished,
the next cycle starts.
During start-up, the capacitor connected to pin COMPPFC is connected by an internal
switch to pin FBPFC which allows it to partially charge before the PFC starts. This reduces
the start-up time.
