PrimAccurate™离线数字PWM N沟道MOSFET控制器

IW1692是一款高性能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。IW1692为移动计算和通信和备用电源等应用的应用程序适用雷竞技安卓下载于电源适配器，符合AC / DC单输出电源（REV 2.0）的Energy-Star®规范，无负载功耗小于150mW。作为一个PrimAccurate™controller, which use primary-side control algorithms, the iW1692 does not need any direct secondary-side feedback components, eliminating the need for opto-isolators, reducing component count and solution cost. Additional features include quasi-resonant control for optimal efficiency at heavy loads, low start-up current, full protection from fault conditions, cable and connector voltage drop compensation and tiny packaging. The iW1692 comes in two options, the iW1692-00 with zero voltage drop compensation and the iW1692-30, with 300mV of voltage drop compensation.
