72kHz integrated 800V BJT optimized for 12Vout

IW1818AccuSwitch™数字PWM转换器与800V BJT电源开关集成高度精确的控制电路，为直线电源转换提供完整的输出功率。

Dialog'sprimAccurate™primary-side digital control algorithms eliminate the need for failure-prone optocouplers and ensure excellent cross-regulation accuracy, to enable the longer operating lifetime, high performance and reduced cost required for white goods applications.

该输出旨在平滑地启动到大电容器中，同时保持快速接通时间。它以准谐振模式运行，以优化效率并采用低功耗模式，实现<50mW的空载功耗以满足全球能效法规。附加功能包括从过度温度，过电压和过电流条件的完全保护以及EZ-EMI®technology to easily meet global EMI specifications.

A迪亚姆simulation model is available for the iW1818. For more information and where to download, please visit the迪亚姆page.
