iW1830-EVAL1: 5V @ 3A, 90 ~ 264V in, Isolated

The iW1830-EVAL1 evaluation board implements a 15W power supply based on Dialog Semiconductor's iW1830 AccuSwitch™ digital offline power supply controller IC. The evaluation board supplies a 5V, 3A regulated output voltage using a primary-side controlled quasi-resonant flyback converter that meets the U.S. Department of Energy's most recent level VI efficiency standard and the EU's Code of Conduct, Version 5, Tier 2 standard for both active mode and no-load standby power consumption.

The iW1830 controller integrates a 700V power MOSFET to lower the power supply BOM cost and uses Dialog's advanced PrimAccurate™ digital control technology to eliminate the need for external secondary-side feedback components, further reducing component count and cost, while improving reliability.

It operates in quasi-resonant mode to improve efficiency and help meet EMI standards. This quasi-resonant operation and Dialog's EZ-EMI® technology enable EMI compliance with minimal external filtering. Proprietary control technology allows high efficiency across a broad range of loads, which enables the iW1830 to meet stringent international standards for power supply efficiency.
