CM6805BG Beschreibung


The CM6805A and CM6806A are the Green-Mode PF/PWM Combo controller for High Density AC Adapter.For the power supply, its input current shaping PFC performance could be very close to the performance of the CM6800 or ML4800 leading edge modulation average current topology.
CM6805/CM6806A offers the use of smaller, lower cost bulk capaitors, reduces power line loading and stress on the switching FETs, and results in a power supply fully compliant to IEC1000-3-2 specifications. The CM6805A/CM6806A includes circuits for the implementation of a leading edge, input current shaping technique"boost' type PFC and a trailing edge, PWM.
The CM6805A's PFC and PWM operate at the same frequency,67.5kHz.A PFC OVP comparator shuts down the PFC section in the event of a sudden decrease in load.The PFC section also includes peak current limiting for enhanced system reliability.
Both PFC and PWM have the Green Mode Functions.
When the load is below GMth, Green Mode Threshold, PFCOUT is turned off. The GMth can be programmed by the designer. PWM Green Mode will happen when the PWMCMP(PWM Comparator) Duty Cycle is less than~6%, in the next cycle, the PWMOUT pulse will be removed until PWMCMP Duty Cycle is greater than 6%, then the next cycle, PWMOUT pulse appears.
PWM has a PWMtrifault pin which can sense the PWM short and determine the GMth to turn off PFC.


 Both PFC and PWM have the Green Mode to meet blue angel and energy star spec.
10-Pin SOIC package

PWM pulse skipping for the green mode

Use RAC as the Startup resistor around 5 Mega Ohm at IAC pin

 It can use the HV bipolar to start up the chip and it helps green mode.
Easy to configure into Boost Follower

 Enable lowest BOM for power supply with PFC

 Internally synchronized PFC and PWM in one IC

 Patented slew rate enhanced voltage error amplifier with advanced input current shaping technique

Universal Line Input Voltage

 CCM boost or DCM boost with leading edge modulation

 PFC using Input Current Shaping Technique

 Feedforward IAC pin to do the automatic slope



 Tr-Fault Detect comparator to meet UL1950
Low supply currents; start-up:100uA typical, operating current:2mA typical.
Synchronized leading PFC and trailing edge modulationPWM to reduce ripple current in the storage capacitor between the PFC and PWM sections and to reduce switching noise in the system

 VINOK Comparator to guarantee to enable PWM when PFC reach steady state

 High efficiency trailing-edge current mode PWM Exact 50% PWMmaximum duty cycle

 UVLO, REFOK, and brownout protection

 Digital PFC and PWM soft start,~10mS

Precision PWM 1.5V current limit for current mode operation

 PWMtrifault to sense DC to DC short and Turn off PFC at GMth

 PWMtrifault also can be programmed to do the Thermal Protection
