The iW1830 AccuSwitch™ digital PWM converter integrates a highly accurate control circuit with a 700V power MOSFET to provide a complete solution for off-line power conversion at up to 15W of output power.
Dialog's PrimAccurate™ primary-side digital control algorithms eliminate 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.
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 as EZ-EMI® technology to meet global EMI specifications.
A DiaSIM™ simulation model (32-bit NL5 version only) is available for the iW1830. For more information and where to download, please visit the DiaSIM™ page.
