高PF，<10％THD，符合IEC61000-3-2兼容，集成启动设备
IW3677前端反激功率因数校正装置使用对话框提供高功率因数（PF> 0.9），低功率因数（PF> 0.9）和低THD（<20％），使用对话框的负载电流PF-Boost™technology. The device can be configured in both isolated and non-isolated configurations, as a buck, buck-boost or flyback converter and consumes less than 150mW no-load standby power at 230VAC. The iW3677 integrates a high-voltage startup device which also reduces standby power consumption during normal operation.
The iW3677 integrates a full range of protection features including output over-voltage, over-power, input over-voltage and under-voltage, over-current and sense resistor short circuit protection, open loop and over temperature protection.
有关无需集成的高压启动，请参阅IW3671.
