The following user guide supports the FAN9611 / FAN9612 400W e valuat ion bo ard 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 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 sw itching 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.

www.fairchildsemi.com for

Built-in protection functions include output over-voltage, over-current, open-feedback, under-voltage lockout, brownout, and redundant latching over-volta ge. 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.
