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.

2 Features

● EZ-EMI^®technology: excellent EMI performance with

● Wide input voltage range: 90V_ACto 264V_AC

a minimum of EMI ﬁltering components

● Output voltage: 5V

● Quasi-resonant operation

● Output current: 3A

● Low component count and small PCB footprint

● Total output power: 15W max.

● iW1830 IC protections:

● Integrated 700V MOSFET

Output short-circuit, over-current, over-voltage

● Active mode efﬁciency > 82%

Input voltage protection: brown-out, brown-in,

unplug

● Supports high capacitance loads up to 6,000mF

● Low no-load power: < 50mW (at 230 V_AC)

Over-temperature protection - internal sensor

3 Applications

● Power Supplies for:

White Goods
