IW1830-EVAL

The IW1830-EVAL from Dialog Semiconductor is an evaluation board implements a dual-output, 15W power supply based on iW1830 AccuSwitch digital offline power supply controller IC. The evaluation board supplies two outputs, 12V/1A and 5V/0.5A, using a single primary-side controlled quasi-resonant flyback converter. The design implements two output voltages using one primary-side controller and achieves the tight regulation required by high-reliability applications. It integrates a 700V power MOSFET to lower the power supply BOM cost and uses Dialog's advanced PrimAccurate digital control technology to eliminate 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 excellent EMI performance with minimal external filtering.
