72KHz集成800V BJT优化5VOUT

The iW1820AccuSwitch™digital PWM controller integrates a highly accurate control circuit with an 800V BJT power switch to provide a complete solution for off-line power conversion at up to 15W of output power.

Dialog’sPrimAccurate™一次侧数字控制算法消除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.

该输出旨在平稳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<30MW的空载功耗以满足全球能效规范。
