CM6805
Overview
- 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
