Dialog CW7270 Evaluation board for 15w single-output switch-mode power supply Datasheet

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 offline 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
●● Wide input voltage range: 90VAC to 264VAC
●● Output voltage: 5V
●● Output current: 3A
●● Total output power: 15W max.
●● Integrated 700V MOSFET

●● Low component count and small PCB footprint
●● iW1830 IC protections:
xx Output short-circuit, over-current, over-voltage
●● Active mode efficiency > 82%
●● Supports high capacitance loads up to 6,000mF
xx Input voltage protection: brown-out, brown-in, unplug
●● Low no-load power: < 50mW (at 230 VAC)
xx Over-temperature protection - internal sensor
3 Applications
●● Power Supplies for:
xx White Goods
xx Home Appliances
xx Industrial Control
xx Network Devices

WARNING
Disclaimer for High Voltage (Mains Powered) Evaluation Boards
Warning
This evaluation board is powered by AC mains voltage. When powered, this
evaluation board generates non-insulated high voltages which may produce
electrical shock, burn, and/or fire hazards, resulting in risk of property damage,
personal injury, and/or death.
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.
TO BE USED FOR EVALUATION PURPOSES ONLY
This board is intended for evaluation purposes only and not intended for commercial use in an end product. Any other
use is strictly prohibited by Dialog Semiconductor.
WORK AREA AND PERSONAL SAFETY
This board should be used in a test area/laboratory specifically designed and designated for working with, and
evaluating high-voltage electrical devices. Only trained and qualified professional personnel with experience,
knowledge and training in the use of high-voltage electrical circuits should use this evaluation board. Trained
personnel must use required personal protective equipment and required laboratory equipment when working with the
evaluation board.
The professional personnel operating this evaluation board and the test area/laboratory in which it is operated must
be qualified according to the local regulations, guidelines and labor laws applicable to working with non-isolated mains
voltages and high voltage circuits.
An isolated housing is highly recommended when using this evaluation board.
Use this evaluation board at your own risk.
NOT AGENCY APPROVED
This evaluation board has not been agency tested or approved for safety, technical performance, and/or regulatory
requirements, such as electromagnetic interference or other technical regulatory or safety requirements.

Note 1:
The iW1830-EVAL1 has been designed to meet UL1310 (up to 120VAC) with the exception of the common mode choke
L4 (see Note 2) and EN60335-1:2012, however individual boards have not been tested or verified to these standards.
Note 2:
The iW1830-EVAL1 uses a common mode choke which is intended for 5V/3A designs that are used as part of circuits
in white goods. Alternative UL-1310 compliant parts should be used if this design is used for a standalone 5V/3A power
unit.
