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

A team of engineers is ready to answer your questions

64kHz integrated BJT, 3.5W output

The iW1810 is a high performance AC/DC converter with an integrated 800V power Bipolar Junction Transistor (BJT). Capable of 3.5W maximum output power, the iW1810 operates in a quasi-resonant mode to optimize efficiency and it also incorporates a power saving mode that enables less than 100mW of power consumption at no load, meeting global energy efficiency standards and making it ideal for applications such as energy standard compliant home appliances. 

The iW1810 also incorporates Dialog's Dialog's proprietary PrimAccurate primary-side digital control algorithms that enable a fully isolated solution without the need for an optocoupler, reducing cost and solution size while greatly improving reliability. Additional functionality includes full protection from over temperature, over voltage and over current conditions as well as EZ-EMI® design techniques to allow for a solution that easily meets global EMI specifications.
