The following user guide supports the FAN9611 / FAN9612 400W evaluation board for
interleaved boundary-conduction mode power factor corrected supply. The user guide
should be used in conjunction with the FAN9611/FAN9611 / FAN9612 datasheet as well
as the Fairchild application note AN-6086 — Design Considerations for Interleaved
Boundary-Conduction Mode PFC Using FAN9611 / FAN9612. The user guide and the
evaluation board can also be used to evaluate FAN9611 controller which has the lower
turn-on threshold. Please visit Fairchild’s website at www.fairchildsemi.com
information.
1. Overview of the Evaluation Board
The FAN9611 / FAN9612 interleaved dual Boundary-Conduction-Mode (BCM) PowerFactor-Correction (PFC) controller operates two parallel-connected boost power trains
180º 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 zerocurrent switching of the boost diodes (no reverse-recovery losses), 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 between the power trains and
effectively doubling the switching frequency.
The advanced line feedforward with peak detection circuit minimizes the output voltage
variation during line transients. To guarantee stable operation with less switching loss at
light load, the maximum switching frequency is clamped at 600kHz. Synchronization is
maintained under all operating conditions.
for
Built-in protection functions include output over-voltage, over-current, open-feedback,
under-voltage lockout, brownout, and redundant latching over-voltage. The FAN9611 /
FAN9612 is available in a lead-free 16-lead SOIC package.
Fairchild offers and evaluation board to aide in design and test of applications using the
FAN9611 / FAN9612. The FAN9611 / FAN9612 evaluation board is a single-layer board
designed for 400W (400V/1A) rated power. Thanks to the phase management, the
efficiency is maintained above 95% at low-line and high-line, even down to 10% of the
rated output power. The efficiencies for full-load condition are 96.3% and 98.0% at line
voltages of 115V
and 230VAC, respectively.

3. Test Procedures
Before testing the board; DC voltage supply for VDD, AC voltage supply for line input,
and DC electric load for output should be connected to the board properly.
1. Supply V
specification for V
2. When V
the inrush current limit relay is turned on by 5V reference (pin #3), the relay turns on
when FAN9611 / FAN9612 comes out of UVLO by supplying V
3. Connect the AC voltage (90~264V
FAN9611 / FAN9612 has brownout protection and line OVP, any input voltages out
of operation range trigger protections.
4. Change load current (0~1A) and check the operation. The board is designed to go
into phase shedding for output power below around 55W. It goes back to twochannel interleaving operation for output power above around 110W.
