The patented interleaved PFC idea was starting around mid 90. The idea was to solve Qrr of 600V Boost diode at CCM. DCM boost does not have the Qrr issues, but DCM boost has much higher ripple current and it increases switching loss and it causes the troubles of EMI circuits. The interleaved PFC, it solves both ends. In the front end, two DCM boost converter currents combine together and it behaves like a CCM with two times the frequency. From the lab data, its efficiency can be above 95% at full load without ultra fast diodes. CRM interleaved PFC can improve the efficiency of PFC further. CRM is ZCS at on time. By delaying the ZCD pin, it can get about ZVS switching. The 180 degree phase shift is done by the internal timer. The PFCOUT (master) is the clock of the timer. The slave PFC does not have to sense any signal if the external boost inductor is matched well. Usually, the PFC sensing resistor value at Isense Slave (pin 9) can use less than the resistor value of the Isense Master (pin 8) PFC sensing resistor. It improves a bit of the efficiency. To make PFC master and PFC slave components matched is important because it can reduce the power device cost. Also, the matched components can be ensured both master and slave PFCs work at CRM mode. Without the good matches, both PFC power device margin needs to over design to cover the worst mismatched condition. Basically, it is like two 6561s work together with 180 degree phase shift + light load improvements. Constant Power and Constant Bandwidth PFC: The Gain Modulator with Vrms2, it keeps the power constant over universal line input. The Vrms1 and Vrms2 are derived from IAC current. By deriving Vrms1 from IAC, it improves the light load efficiency and it reduces the circuit and part counts. The product of Gain Modulator output current and Rmul determines the sine wave current and the maximum value is about 500mV. Boost Light Load Efficiency: CM6565 is designed for both 90+ systems or 85+ systems. For 90+ systems, CM6565 interleaved CRM PFC is ready to interface with CM6900 which is a secondary SRC+SR controller or it can be interfaced with CM6901 which is a secondary LLC+SR controller. At light load, CM6565 will drop the PFC bulk voltage from 380V to 342V and the slave PFC will be disabled. Only the master PFC is on during the light load condition. Boost Light Load Functions can be disabled by clamping pin 6 (SS) below 5V. 2008/10/09 Rev1.0 Champion Microelectronic Corporation Page 10 CM6565 Noise Free 16 pin Self-Start Interleaved PFC with 180 Degree Phase Shift CRM PFC Controller for 90+/85+ IAC (PIN 1): IAC serves several functions: During the system Start-Up, IAC pin is connected to VCC; therefore, the external RAC which is between IAC and line input voltage can be served as a Start-Up resistor (bleed resistor). Once VCC is greater than UVLO, 13V, IAC pin will be connected to the multiplier input which is a current mirror and IAC voltage is about 1.4V. Usually, the value of the RAC is between 4 Mohm to 10 Mohm. Green Mode with Fast Start Up with high voltage bipolar and low voltage diode. The following circuit can be used for the Fast Start Up, if the on time needs to be less than 100mS and Green Mode Performance is needed. RIVCCLIMIT RAC 1 50K 4M Q1 NPN RAC 2 Line Input Voltage 100K IAC DLOWVOLTAGE VCC After VCC is greater than UVLO, IAC is connected to the input of the current mirror which is also the input of the multiplier. This current input multiplier is less sensitive to the noise since it is sensing current instead of the voltage, not like the conventional voltage input multiplier which senses the voltage and requires a two resistor network to sense the line input voltage information. 2008/10/09 Rev1.0 Champion Microelectronic Corporation Page 11 CM6565 Noise Free 16 pin Self-Start Interleaved PFC with 180 Degree Phase Shift CRM PFC Controller for 90+/85+ Vrms1 (PIN 4) and Vrms2 (PIN 5) Vrms1 and Vrms2: These two pins will represent the rms value of the line input voltage information without using additional high voltage resistors. Vrms1 will take the IAC current + RC filters to obtain the voltage level with the first pole and the first pole frequency is about 12Hz. The second RC pole level at about 5 Hz is the Vrms2 level. Vrms1 takes this voltage information to determine the AC Brown Out Level. When Vrms1 is above 3V, both PFCout(master) and PFCout(slave) start with Veao Soft Start. When Vrms1 is below 2V, both Veao and SS are pulled down. Vrms2 also is the input of Gain Modulator which provides the about constant power limit. The average value of 2 x Vrms2 needs to equal to the average value of the Vrms1. VFB (PIN 15) VFB also serves several functions: 1. Transconductance Amplifier speed up the load transient and the line transient. 2. VFB PIN is the inverting input of Transconductance Amp, GM. 3. Fast and Precision PFC Over Voltage Protection 4. CM6565 is implemented with GM; therefore, it does not require a local feedback (Which is a must item for the Conventional Operational Amplifier.) Its compensation network is connected between VEAO and GROUND and there is not feedback compensation network between VEAO and VFB. 5. Since there is no local feedback between VEAO and VFB, the VFB node can sense the PFC output voltage without any delay; not like the conventional operational amplifier (It has 100mS time constant. This may stress the 380V PFC output capacitor.) CM6565’s PFCOVP use the VFB pin to sense the PFC over voltage condition without any delay. 6. Comply with UL1950, single fault protection without any additional external circuit. At VFB pin, CM6565 has been implemented with the tri-fault protection circuit to ensure the system power supply can comply with the UL1950. VEAO (PIN 16) VEAO is the output pin of GM. It can be used as the conventional OP but we not suggest because it will dramatically slow down the system speed. For the proper usage of the VEAO, the compensation network should be connected between VEAO and GROUND. VEAO pin also is the input pin of the low-power-detect comparator. When VEAO potential goes low, it means the power supply system needs less power. When VEAO potential goes high, it means the power supply system needs more power. VEAO potential represents the power status of the power supply. CM6565 uses the VEAO potential to determine if the power supply is at either the light load or the heavy load. ZCDmaster (PIN 2) The master PFC will determine when the slave PFC to turn on. The ZCDmaster sense the demagnetized winding signal from the master PFC boost inductor and its threshold is 80mV. It does not require a diode to rectify the signal. ZCDmaster is clamped between -0.7V to +0.7V by two back-to-back diodes to ground. Do not sink or source more than 100uA. An RC filter may be needed to obtain the best ZVS performance while ZCS is sure thing. Layout notice : the resister of connect the inductor and IC must be close to IC (pin2). 2008/10/09 Rev1.0 Champion Microelectronic Corporation Page 12 CM6565 Noise Free 16 pin Self-Start Interleaved PFC with 180 Degree Phase Shift CRM PFC Controller for 90+/85+ ISENSE master (PIN 8) and ISENSE slave (PIN 9) Usually, ISENSE slave sensing function is reduced by reducing the PFC slave sensing resistor value to be less than 50% value of PFC master sensing resistor. Adding a much smaller value of PFC slave sensing resistor is to protect against any catastrophic fault conditions. The ISENSE master is comparing the product of Gain Modulator Output current and Rmul and it provides the sine wave envelope to obtain the sine wave input current. The maximum threshold voltage, which is the product of Gain Modulator output current and Rmul, is about 500mV. A RC filter which has a 500Khz pole needs to be applied to avoid false triggered by the switching noise. VCC (PIN 13) CM6565’s turn on and turn off VCC is like the other PFC product family; on at 13V and off at 10V. It has 50mA zener/shunt regulator threshold at ~ 16.75V at VCC. The minimum bypass capacitor should be greater than 1uF. Vref (PIN 14) Vref is 1% 3mA buffered 7.5V reference. It requires a 0.1uF to 0.01uF bypass capacitor to filter out the switching the noise. SS (PIN 6) SS pin 6 is the Soft Start Capacitor pin. CM6565 SS pin provides a close loop soft start for the interleaved CRM PFC. The Charging Current is about 8uA. By clamping SS below 5V, it disables the 380V to 340V function at light load and both Master and Slave are on at light load. When SS is above 5V, both light load functions are enabled. 2008/10/09 Rev1.0 Champion Microelectronic Corporation Page 13 CM6565 Noise Free 16 pin Self-Start Interleaved PFC with 180 Degree Phase Shift CRM PFC Controller for 90+/85+ Interleaved CRM PFC (CM6565) Application Circuit D28 HER108 D29 HER108 2 t 380VDC MD1 6 9 RT1 2.5Ω/5A ER806 ZCD_Vcc 12 1 5 + 12 - 4 2 4 R1 2.2M SD1 ST1 400uH VCCP R5 30k R4 2.2M Q1 2N2222 C27 104pF R6 1M 1 C9 220uF/450V VCCP MQ1 R8 11N60 10 Q2 2N2222 C28 104pF 3 R2 2.2M 2 R9 10 1 Q6 2N2907 1 1 D4 1N4148 R11 10K R12 PFC Slave 0.075 Q7 2N2907 1 3 2 PFC Master R3 2.2M ISense Master 2 R7 500K 3 Q5 GMBTA44 SQ1 11N60 2 2 1 D5 1N4148 ISense Slave R13 10K R14 0.075 3 C74 C4 ER806 3 C73 3 C72 2 0.47uF/400V FG 0.47uF/400V 3 2 C3 MT1 400uH L4 10uH 1 0.47uF/400V 4 C1 0.56uF/250V BD1 D10XB60 0.47uF/400V 1 2 3 D12 1N5406 3 1 2 3 T2 CM1 1 JA1 ACINJET 0.22uF/250V F1 Fuse/250V5A D10 R15 100k 1N4148 VCCP R38 22K U1 CM6565 PFC Master 1 2 R40 2.2M 3 4 C16 474pF C26 474pF R24 100K R23 3K R23-1 75K 5 6 C25 R20 103pF NC C18 104pF 7 R33 NC R23-2 10K 8 IAC VEAO ZCDmaster VFB PG THL Vref Vrms1 VCC Vrms2 PFCOUT(Master) SS PFCOUT(Slave) PGB GND Isense Master Isense Slave 16 15 14 13 VCCP 12 PFC Master 11 PFC Slave C13 C10 R10 104pF 102pF 68K R41 47K R17 430K C12 473pF C11 0.47uF 10 9 R25 4.7K ISense Slave ISense Master R26 4.7K R37 10k C20 47pF D7 1N4148 C19 47pF D6 1N4148 Q8 2N2222 2 VCCP + C14 10uF/25V Champion Microelectronic Corporation D8 FM100 3 1 VREF 2008/10/09 Rev1.0 R39 1M 4.7K R22 D11 15V ZCD_Vcc C15 10uF Page 14 CM6565 Noise Free 16 pin Self-Start Interleaved PFC with 180 Degree Phase Shift CRM PFC Controller for 90+/85+ CM6565 + CM6901 Ninety-three Plus Desk Top Application Circuit D28 HER108 PFC D29 HER108 1 J2 PIN 380VDC F1 Fuse/250V5A MT1 400uH 1 2 3 R1 2.2M C74 ST1 400uH 3 2 R7 500K 1 MQ1 11N60 D4 1N4148 2 ZD6 HZ9C3 TA 1 C69 1uF/50V Q1 2N2222 1 R11 10K Q6 2N2907 Q7 2N2907 R12 0.075 R9 10 D5 1N4148 1 3 PFC Master Q2 2N2222 C9 220uF/450V SQ1 11N60 2 3 Q26 2SD667 R8 10 1 R6 1M R92 1K R3 2.2M C71 1uF C70 1uF 3 R4 2M SD1 ER806 VCCP VCCP 2 R2 2M VCCP D23 1N4148 ER806 R13 10K C10 102pF R34 47K R10 62K R14 0.075 JP18 JUMP 3 3 MD1 D24 1N5406 2 4 C73 0.47uF/400V 1 0.47uF/400V 2 C72 4 L4 10uH 1 2 C4 RT1 2.5Ω/5A RL1 835NL-1A-B-C 9V 1 2 + 0.47uF/400V 1 t - 0.47uF/400V 3 Bead 4 3 4 1 1 CM1 L H15 2 BD1 D10XB60 C5 220pF/250VAC Bead C3 0.22uF/250VAC C6 220pF/250VAC T2 4 2 N H14 R15 HS R38 2 R39 1M 22K HS C25 103pF PFC Master R90 2.2M Vrms1 C77 102pF 3 4 C16 0.47uF R23-2 10K PG THL Vref VCC PFCOUT(Master) SS 7 R33 NC VFB Vrms2 6 PGIB/1 C18 1nF R23-1 75K VEAO ZCDmaster Vrms1 5 R23 3K CM6565 IAC 2 R20 NC R24 100K C17 0.47uF U1 1 PFCOUT(Slave) PGB 8 PFC Slave R17 430K GND Isense Master Isense Slave 16 15 Vref/1 VCCP 14 C13 104pF 13 12 11 C23 0.1uF PFC Slave + Vref/1 C14 47uF/25V PC1A 817C C19 47pF 10 R41 10K PGIB/1 9 D7 1N4148 12VS R40 4.7K PFC Master D6 1N4148 PGI R42 1K R25 4.7K 1 3 HS5 R45 3M HS C30 NC 5% C28 100uF/25V 11.5TS 8 8TS 4 5 .
