Overview
R8CB05BO 10-PIN Green-Mode PFC/PWM Combo CONTROLLER GENERAL DESCRIPTION The R8CB05BO is the Green-Mode PFC/PWM Combo controller for Desktop PC and High Density AC Adapter.
For the power supply, it’s input current shaping PFC performance could be very close to the performance of the CM6800 or ML4800 leading edge modulation average current topology.
R8CB05BO 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 R8CB05BO includes circuits for the implementation of a leading edge modulation, input current shaping technique “boost” type PFC and a trailing edge modulation current, PWM.
The R8CB05BO’s PFC and PWM operate at the same frequency, 100kHz.
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.
PFC has a PFCOFFB p...
