iW1830-EVAL1
Evaluation Board for 15W Single-Output
Switch-Mode Power Supply
1 Description
The iW1830-EVAL1 evaluation board implements a 15W power supply
based on Dialog Semiconductor’s iW1830 AccuSwitch™ digital off-
line 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.
