INTRODUCTION
Generally, Schottky diodes traditional devices passive rectification order have conduction loss secondary side switching power supplies. proliferations synchronous rectification (SR) idea which mostly buck-derive topologies have reached domain flyback application recent years. low-voltage-low-Rdson mosfet become attractive replace Schottky rectifiers high current applications because offers several system advantages such dramatic decrease conduction loss better thermal management whole system reducing cost investment heat sink space. number techniques implementation flyback converters continuously growing from simple self-driven (secondary winding voltage detection) more complex solution using "current transformer sensing" combinations both improve existing technology. idea become quite complicated though additional discrete devices have made cost part counts issue even worse. Moreover, issue reverse current conduction (-due delay sensing sharp drop secondary current during turn-off phase still lingers different input line/ output load conditions. simple fast-rate-direct-sensing voltage drop across mosfet (Vsd) using integrated solution pave much simpler effective means controlling mosfets well alleviating reverse current multiple-pulse gate turn-ON issues. objective this user guide show advantages application using integrated approach study practical limits efficiency improvements normal rectification method.

CIRCUIT DESCRIPTION
design basically optimized test platform evaluate active rectification using Smart synchronous rectification well basic features flyback converter operating quasi-resonant mode. This demo board 2-pin connector CON1 input time-lag type 3.5A fuse input current overload protection. Minimum input filtering provided (Cp1-Xcap) before input voltage (90-264VAC) routed 6Amp-bridge rectifier (DB1). Primary side controller (U2) basically drives primary Mosfet operate CriticalConduction mode eliminate turn-ON switching loss thru (zero voltage switching only occurs when NVsec Vdcin thru low-voltage switching when nVsec< Vdcin) reduce capacitive losses especially high line condition. switching frequency full load varies from ~76kHz typically from high input condition falls back minimum value (fixed -10kHz) reduce input power during light load condition. Auxiliary winding loosely monitored demagnetization pin4 through Dp3, Rp11 network that sets limit with Rp11 sets over power limit converter. Resonant capacitor added augment overall parasitic winding capacitance primary mosfet Q1's Coss achieve high input line condition respectively. Optocoupler provides isolated output voltage feedback primary side. output voltage level across load connector CON2 (+16Vo) monitored regulated Secondary error amplifier (AQ105 AS4305) that also manages output current limiting function monitoring voltage across RS25-26 current sense resistors. power stage secondary using 2-SO8 IRF7853 synch-fets (SR) parallel implement low-side synchronous rectification. this configuration, simpler derive supply (IR1166 SO8-IC) controller directly from output Vout. Jumper used isolate U1's from Vout that user easily evaluate IC's power consumption especially during standby load condition. absence sensitive current probe, quiescent current through calculated from differential voltage across Rs17. decoupling capacitor Cs17 Cs18 provides additional filtering which necessary clean high frequency noise especially when driving several mosfets (SR1 SR2) with high parameters normally associated with high currentlow voltage mosfets. sense pins monitor voltage (Vsd) across sync rect mosfets proper attention taken during routing ensure integrity differential voltage Vsd. This done directly taking signal from drain pins SR1//SR2 using dedicated trace. Probe points well redundant test hook points provided facilitate easy probing essential test waveforms.

CIRCUIT FEATURES
setting:
Offset Voltage Threshold easily selected changing position jumper according system mode operation shown Table below. Since demo board practically designed operate Critical conduction mode, left floating grounded prolong MOSFET's channel conduction period compared connecting Vcc. result, this would give advantage further reducing conduction period MOSFET's (SR1 SR2) body diode, thus achieving more efficient operation. Reducing chance having reverse current during fast turn-off phase sync-fets another strong reason having this feature available. Table System mode operation connected CrCM Ground, VTH1= -3.5mV Boundary Floating, VTH1= -10.5mV VCC, VTH1= -19.0 general observation during light load condition (~10-20% full load) that ~0.5 ~1.2% efficiency improvement seen OVT=Gnd compared OVT=floating. This small difference longer significant when load becomes heavy CrCM operation.
Enable setting:
enabled default knowing that tied internally through resistor. Having jumper location will connect will immediately disable internal gate drive circuit IR1166 putting jumper in/out would help user quickly evaluate effect efficiency investigating change input power result having fets working compared just having ordinary passive rectification offered body diode(s) when gate drive disabled. CAUTION This demo board basically designed evaluation functionality IR1166 users disable shorting quick testing full load with care should taken. strongly advise load more than 6Amp with IR1166 disabled prolong period time (>1min). This prevent damaging MOSFET's body diode overheating when load current passes through mosfets' body diode while turned-OFF. Never power-up unit without shorting
Minimum Time (MOT) setting:
setting used de-sensitize from multiple change during turn-ON phase which cause ringing secondary winding voltage (Vsec). adjusted through Rs18 (according AN1087 simplified equation RMOT 2.5x1010 *tmot chosen which usually enough ignore parasitic noises quasi-resonant switching converters such this demo board.

Mosfet Selection Design Tips
Application note AN1087 made easy understand calculations required flyback sync-rect driving circuits using IR1166 Choosing right mosfet(s) satisfy performance-cost requirement sync rect design should simple well. Voltage rating: should also follow similar equation most flyback design shown below:
k*[Vo +(VDCinmax /(Npri/Nsec) where =1.1 guard band
startup stress leakage spike. RdsON rating: Generally, easy meet system efficiency improvement conduction loss becomes twice smaller than normal passive rectification approach. This achieve better thermal performance especially designer wishes consider having bulky heavy heatsink design, take note that would still largely dependent size copper area allotted SRs. should also consider estimated Rdson 25°C (normally shown datasheet) would approximately ~1.8 times higher Tj=125°C. rule thumb, will base calculation these assumptions simplify mosfet selection criteria. typical 100V Schottky rectifiers, around @Tj=125°C), this case should find 100-V mosfet(s) with lower Rdson which will have ~150mV rated full load current (Ioave). quick estimation Isecrms, designer might find Fig. useful quickly estimate Isecrms since Ioave normally given standard design specs.
