iW1830-EVAL
Evaluation Board for 15W Dual-Output
Switch-Mode Power Supply
1 Description
The iW1830-EVAL evaluation board implements a dual-output, 15W power
supply based on Dialog Semiconductor’s iW1830 AccuSwitch™ digital off-
line 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 such as white goods, home appliances and industrial control.
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 excellent EMI performance 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.
