PrimAccurate™ Off-Line Digital PWM Controller
IW1690是一个高性能AC / DC控制器,旨在驱动外部电源双极连接晶体管(BJT),用于峰值电流模式PWM反激电源。IW1690的移动计算和通信和备用电源等应用的应用适用于应亚博国际官网平台网址用的适用性,提供小于150mW的负载功耗。作为使用初级侧控制算法的PrimAccurate™控制器,IW1690不需要任何直接的二级反馈组件,从而消除了对光耦合器的需求,降低了组件计数和解决方案成本。附加功能包括对话的专有EZ-EMI™技术,准谐振控制,用于重负荷,电缆和连接器电压降补偿选项的最佳效率,以及完全保护故障情况。IW1690有七种不同的开关频率组合(45kHz,65kHz或75kHz),电缆补偿电压(0mV至412mV)。
