CM6805B

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
