72kHz集成800V BJT，为12Vout优化

The iW1818AccuSwitch™digital PWM converter 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 12W of output power.

对话框的PrimAccurate™一次侧数字控制算法消除了对容易发生故障的光耦的需要，并确保了出色的交叉调节精度，从而实现了白色家电应用所需的更长的工作寿命、高性能和更低的成本。亚博国际官网平台网址

The output is designed to smoothly start-up into large capacitors while maintaining a quick turn-on time. It operates in quasi-resonant mode to optimize efficiency and incorporates a low-power mode that achieves <50mW of no-load power consumption to meet global energy efficiency regulations. Additional features include full protection from over-temperature, over-voltage and over-current conditions as well asEZ-EMI®轻松满足全球EMI规范的技术。
