Description
The FAN9611 interleaved dual Boundary-Conduction-
Mode (BCM) Power-Factor-Correction (PFC) controller
operates two parallel-connected boost power trains 180?
out of phase. Interleaving extends the maximum practical
power level of the control technique from about 300 W to
greater than 800 W. Unlike the continuous conduction
mode (CCM) technique often used at higher power
levels, BCM offers inherent zero-current switching of the
boost diodes, which permits the use of less expensive
diodes without sacrificing efficiency. Furthermore, the
input and output filters can be smaller due to ripple
current cancellation and effective doubling of the
switching frequency.
The converters operate with variable frequency, which is
a function of the load and the instantaneous input /
output voltages. The switching frequency is limited
between 16.5 kHz and 525 kHz. The Pulse Width
Modulators (PWM) implement voltage-mode control with
input voltage feedforward. When configured for PFC
applications, the slow voltage regulation loop results in
constant on-time operation within a line cycle. This PWM
method, combined with the BCM operation of the boost
converters, provides automatic power factor correction.
The controller offer bias UVLO of 10 V / 7.5 V, input
brownout, over-current, open-feedback, output over-
voltage, and redundant latching over-voltage protections.
Furthermore, the converters output power is limited
independently of the input RMS voltage. Synchronization
between the power stages is maintained under all
operating conditions.
