[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 MM3669.
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.
MM3669 has 2 gate driver, this constitution is specialized in Half-Bridge LLC resonant converter.
MM3669 controls turn-ON/OFF of MOSFET by detecting the voltage between drain and source of MOSFET.
This turn-OFF threshold voltage is adjustable by the external resistor.
MM3669 has safety controller for LLC converter, as an example, preventing that VG is turned on at the same time.
This IC uses SOP-10A package and supports flow conditions.
