The Synchronous Rectification control IC for AC-DC converter MM3667 Series
The Synchronous Rectification control IC for AC-DC converter
Monolithic IC MM3667 Series
Outline
This IC is secondary side synchronous rectification control IC to drive MOSFETs in isolated AC-DC converter. It is able to achieve very high efficiency by replacing secondary rectifier diode with MOSFET and MM3667. It is possible to correspond to various efficiency restrictions. And it is effective for the miniaturization of the power supply by the heat sink reduction and so on. MM3667 Supports the Half-Bridge LLC resonant converter and Quasi-Resonant flyback converter. MM3667 controls Turn-ON/OFF of MOSFET by detecting the voltage between Drain and Source of MOSFET.
