72KHz集成800V BJT优化12VOUT

The iW1818一种ccuSwitch™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™初级侧数字控制算法消除了对易于光电耦合器的需求，并确保出色的横向精度，以实现更长的操作寿命，高性能和白色商品应用所需的成本降低。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®.技术可轻松满足全球EMI规范。

一种DiaSIMsimulation model is available for the iW1818. For more information and where to download, please visit theDiaSIMpage.
