primAccurate™Off-Line Digital PWM N-Channel MOSFET Controller

The iW1692 is a high performance AC/DC controller designed to drive an external power N-channel MOSFET for peak current mode PWM flyback power supplies. Ideal for power adapters for applications such as mobile computing and communcations and standby power supplies in consumer electronics, the iW1692 meets the Energy-Star® specification for AC/DC single output power supplies (rev 2.0) with no-load power consumption less than 150mW. As aprimAccurate™控制器使用初级侧控制算法，IW1692不需要任何直接的二级反馈组件，从而消除了光隔离器的需求，降低了组件计数和解决方案成本。附加功能包括准谐振控制，以实现重载，较低的启动电流，全面保护免受故障条件，电缆和连接器电压降补偿和微小包装。IW1692有两种选择，IW1692-00具有零电压降补偿和IW1692-30，具有300mV的电压降补偿。
