www.fairchildsemi.com © 2010 Fairchild Semiconductor Corporation 3 FEB279_FAN9611/12 • Rev. 0.0.2 The following user guide supports th e FAN9611/12 400W evaluation board for interleaved boundary-conduction-mode power-factor-corrected supply. It should be used in conjunction with the FAN9611/12 datasheet as well as the Fairchild application note AN-6086 Design Considerations for Interl eaved Boundary-Conduction Mode PFC using FAN9612. Although marked FAN9612, the evaluation board can be interchangeably used to evaluate either the FAN9611 (10V turn -on threshold) or FAN9612 controller (12.5V turn-on threshold). Please visit Fairchild’s website at www.fairchildsemi.com for additional information. 1. Overview of the Evaluation Board The FAN9611/12 interleaved dual Boundary -Conduction-Mode (BCM) Power-Factor- Correction (PFC) controllers operate two pa rallel-connected boost power trains 180º out of phase. Interleaving extends the maximu m practical power level of the control technique from about 300W to greater th an 800W. Unlike the continuous conduction mode (CCM) technique often used at higher power levels, BCM offers inherent zero- current 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 curren t cancellation between the power trains and doubling of effective switching frequency. The advanced line feedforward with peak de tection 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 525kHz . Synchronization is maintained under all operating conditions. Protection functions include output over-voltage, over-current, open-feedback, under- voltage lockout, brownout, and redundant la tching over-voltage protection. The FAN9611/12 is available in a lead-free 16-lead SOIC package. This FAN9611/12 evaluation board is a four-l ayer board designed for 400W (400V/1A) rated power. Thanks to the phase management , the efficiency is maintained above 96% at low-line and high-line, even down to 10% of the rated output power. Efficiency is 96.4% at line voltage 115V AC and 98.2% at 230VAC under full-load conditions.

Specifications This board has been designed and optimized for the following conditions: Input Voltage Range Rated Output Power Output Voltage (Rated Current) VIN Nominal : 85~264VAC VDD Supply : 13VDC~18VDC 400W 400V-1A Note: 1. Minimum output voltage during the 20ms hold-up time is 330V DC. VLINE = 85~264VAC VOUT = 400V fSW > 50kHz Efficiency > 96% down to 20% load (115VAC) Efficiency > 97% down to 20% load (230VAC) PF > 0.99 at full load The trip points for the built-in protections are set as below in the evaluation board. The non-latching output OVP trip point is set at 108% of the nominal output voltage. The latching output OVP trip point is set at 117% of the nominal output voltage. The line UVLO (brownout protection) trip point is set at 68VAC (10VAC hysteresis). The pulse-by-pulse current limit for each MOSFET is set at 9.1A. The maximum power limit is set at ~120% of the rated output power. The phase management function permits phase shedding/adding ~15% of the nominal output power for high line (230VAC). This level can be programmed by modifying MOT resistor (R6).
