Description
The FAN9611/12 family of interleaved dual Boundary Conduction-Mode (BCM)
Power-Factor-Correction (PFC) controllers operate two parallel-connected boost
power trains 180° out of phase. Interleaving extends the maximum practical
power level of the control technique from about 300W to greater than 800W.
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 16.5kHz and 525kHz. 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 controllers offers bias UVLO (10V / 7.5V for FAN9611 and 12.5V / 7.5V for
FAN9612), 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.
