可选电缆滴补偿

The iW1762 is a high performance AC/DC controller designed to drive an external power N-channel MOSFET for peak current mode PWM flyback power supplies. Optimized for power supplies with output power between 15W- 24W, the iW1762 is ideal for power adapters in networking equipment and monitors.

The iW1762 easily meets the US DoE’s external power supply standard and the EU’s Code of Conduct, version 5, tier 2 standard, with no-load power consumption less than 20mW while complying with active mode efficiency requirements. As aprimAccurate™控制器IW1762不需要任何直接的辅助反馈组件,无需光耦合器,降低组件计数和解决方案成本。其他功能包括对话框的专有EZ-EMI™技术,自适应多模PWM / PFM控制,以实现所有负载的最佳效率,5个可选电缆和连接器电压降补偿电压,鲁棒操作,完全保护免受过电压和过温。
