IW1830-EVAL1

The IW1830-EVAL1 from Dialog Semiconductor is an evaluation board implements a single output, 15W switch mode power supply based on 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. 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.
