GENERAL DESCRIPTION

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

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.

Mismatches between two boost converters for the

interleaved PFC can be less than +/-5%.

Basically, it is like two 6561s work together with 180

degree phase shift plus light load improvements.

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.

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.

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.

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.

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.
