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.

2 Features
