iW1812

AccuSwitch™ Off-Line Digital PWM Converter with 800V Bipolar Power Transistor

A team of engineers is ready to answer your questions

64kHz integrated BJT optimized for 5Vout, 5W output

The iW1812 is a high performance AC/DC converter with an integrated 800V power Bipolar Junction Transistor (BJT). Capable of 5W output power, the iW1812 operates in a quasi-resonant mode to optimize efficiency and it also incorporates a low-power mode that enables less than 30mW of power consumption at no load, meeting global energy efficiency standards, making it ideal for applications such as energy standard compliant home appliances.

The iW1812 also incorporates Dialog'sPrimAccurate初级侧数字控制算法,可实现完全隔离的解决方案,无需光耦合器,降低成本和解决方案尺寸,同时大大提高可靠性。附加功能包括从过度的温度,过电压和电流条件的完全保护以及EZ-EMI®设计技术允许容易满足全球EMI规范的解决方案。
