Overview
CM6805(A;B)/CM6806A 10-PIN Green-Mode PFC/PWM Combo CONTROLLER for High Density AC Adapter GENERAL DESCRIPTION FEATURES The CM6805A and CM6806A are the Green-Mode ‹ PFC/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.
‹ CM6805A/CM6806A offers the use of smaller, lower cost bulk capacitors, 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 limi...
