Selectable cable drop compensation
IW1762是一个高性能AC / DC控制器,旨在驱动外部电源N通道MOSFET,用于峰值电流模式PWM反激电源。IW1762为11W-24W之间的输出功率优化,是网络设备和监视器中的功率适配器的理想选择。
IW1762轻松符合美国DOE的外部电源标准和欧盟的行为准则,5,第2层标准,无负载功耗小于20mW,同时符合主动模式效率要求。作为一个PrimAccurate™controller the iW1762 does not need any direct secondary-side feedback components, eliminating the need for optocouplers, reducing component count and solution cost. Additional features include Dialog's proprietaryEZ-EMI™technology, adaptive multi-mode PWM/PFM control for optimal efficiency across all loads, 5 selectable cable and connector voltage drop compensation voltages, robust operation with full protection from over-voltage and over-temperature.
