Noise Free 16 pin Self-Start Interleaved PFC with
180 Degree Phase Shift CRM PFC Controller for 90+/85+
GENERAL DESCRIPTION
FEATURES
The CM6565 is the industry first 16 pin self-start interleaved
PFC with 180 degree phase shift CRM PFC controller for
total power supply system efficiency greater 90% or 85%.
The CM6565 is like a combination of two 180 degree
phase shift CM6561s plus a lot of light load efficiency boost
functions. CM6565 gives the best noise free performance of
the offline power supply. The desired frequency range for
each PFC controller should be above 35KHz.

#5,804,950, #5,798,635, #6,091,233
Industry first interleaved PFC with 180 phase shift
CCM for EMI filter but CRM for PFC boost diodes
Due to ZCS and about ZVS, it is about noise free
Design for LCD TV or 90+ power supply
Critical Conduction Mode (CRM) = ZCS with about ZVS
Current input multiplier, IAC (Patented)
For 90+ system, an LLC or SRC should be the PWM
For 85+ system, an Dual Forward or a half bridge should be
the PWM
Mismatches between two boost converters for the
interleaved PFC can be less than +/-5%.
At light load, PFC bulk will drop ~ 40V at low line and Slave
PFC will be disabled (Patented)
Basically, it is like two 6561s work together with 180
degree phase shift plus light load improvements.
PGB pin also can be used to turn on the CM6900/CM6901
which is LLC/SRC controller for 90+ applications
VRMS does not need high voltage resistor; IAC determines
VRMS1 and VRMS2
1. IAC (pin 1), Multiplier input pin: Current input instead of
Voltage input; it will enhance input current THD and the
system will be less sensitive to the noise. The system can
reduce one resistor between ground and IAC, multiplier
input pin.
AC Brown out by comparing VRMS2 with 1.25V on and
1.0V off
2. IAC (pin 1), Multiplier input pin: During the start up
condition (the VCC is less than UVLO, 13V), IAC is
connected to VCC, and the RAC resistor (between VIN pin
and IAC pin) serves as a bleed resistor. Once the VCC is
greater than UVLO, then, RAC resistor provides the sine
wave current from VIN pin to IAC pin. After VCC is greater
than UVLO, the voltage of the IAC pin is around 1.4V.
Therefore, the RAC resistor can be served as a bleed
resistor. Usually, the value of the RAC is from 4Mega to
10Meg ohm.
No bleed resistor during the start up (Patented)
Can ON-OFF high voltage bipolar during the system start
up (Patented)
500mV Current Limit and about 130uS Current Loop Open
time out protection
Precision output over voltage protection comparator with
2.75V threshold which is 10% increased from 2.5V.
GM for Fast line and load transient response (Patented)
Soft Start pin at pin 6
Open control loop protection/Tri-Fault Detect Comparator
for UL1950 (Patented)
3. IAC (pin 1), Multiplier input pin: During the start up, if the
system turn-on time needs to be fast, an external high
voltage bipolar and a diode can be added for VCC during
the start-up, once VCC is greater than UVLO, 15V, IAC pin
will go low and turn off the high voltage bipolar.
16.5V 50mA Shunt Regulator at VCC
Micro power start-up current (60uA Typ.)
Very low operating supply current (1.5mA Typ.)
Internal start up timer
4. For the fast load transient and line transient, a
transconductance error amplifier has been implemented
between the output pin VEAO and the input pin VFB to
replace the conventional OP. Since transconductance
amplifier does not need the local feed back (OP needs the
local feedback); therefore, its VFB can fast and accurately
sense OVP condition not like traditional OP, operational
amplifier can not sense VFB for OVP.

5. Open Control Loop protection/Tri-Fault Detect
Comparator on VFB pin for easy passing the single fault
protection test of the UL1950 regulation.
The CM6565’s interleaved PFC has two PFC controllers,
Master PFC and Slave PFC. The Slave PFC is lagged ~
180 degree phase shift from the Master PFC. Both PFC
controllers consisted of ZCS plus about ZVS functions. It
provides the high efficient of power supply at both full load
and at light load. To input EMI filter, the currents are
overlapping and it looks like a CCM boost system with
double frequency. The ZCS plus about ZVS on feature
reduce the EMI noise further.
It has a superior performance multiplier making the device
capable of working in universal input voltage range
applications with an excellent THD.
The totem pole output stage is capable of driving a power
MOS or IGBT with +500mA source and -1A sink currents.
The device is operating in transition mode and it is
optimized for Electronic Lamp Ballast application, AC-DC
adaptors and SMPS.

CM6565
Noise Free 16 pin Self-Start Interleaved PFC with
180 Degree Phase Shift CRM PFC Controller for 90+/85+
Interleaved PFC:
CM6565 is the industry first interleaved PFC. 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.

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.

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.

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).

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.
