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.

Warnings

When the evaluation board is powered, never touch the board or its electrical circuits since they may be operating at high voltages that can cause an electrical shock hazard.
