Dialog CC1206KKX7RBBB471 Evaluation board for 10w single-output switch-mode power supply Datasheet

iW1818-EVAL
Evaluation Board for 10W Single-Output
Switch-Mode Power Supply
1 Description
The iW1818-EVAL evaluation board implements a 10W power supply based
on Dialog Semiconductor’s iW1818 AccuSwitch™ digital off-line power supply
controller IC. The evaluation board supplies a 5V, 2A 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 iW1818 controller integrates an 800V power BJT transistor 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 iW1818 to meet stringent international standards for power supply efficiency.

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.
