离线数字绿色模式准谐振PWM控制器

The iW1709 digital off-line controller offers fast start-up into high capacitive loads, very low standby power consumption (<50mW) and a cost-optimized BOM, working with low-cost BJT power devices for off-line power supplies up to 12W. By meeting the U.S. Department of Energy’s external power supply efficiency requirements and Version 5, Tier 2 of the EU’s Code of Conduct for external power supplies, the iW1709 fits ideally into home networking equipment, home appliances, wireless access points and set-top boxes.

整合对话框primAccurate™andEZ-EMI®技术支持易于设计的解决方案，并通过消除外部光学反馈隔离器的需求来降低BOM成本。IW1709还集成了电缆掉落补偿选项，请补偿电缆和连接器中的电压降，确保正确的电压使其成为负载。保护功能的完整补充使得在短路，过电压，输入欠压或过温条件的情况下，可以实现鲁棒操作。
