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 Semiconductors 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 Dialogs 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 Dialogs 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 EZ-EMI technology: excellent EMI performance with Wide input voltage range: 90V to 264V AC AC a minimum of external EMI filtering components Output voltages: 12V and 5V Quasi-resonant operation Output current: 12V - 1A, 5V - 500mA Low component count and small PCB footprint Total output power: 15W max. iW1830 IC protections: Integrated 700V MOSFET x Output short-circuit, over-current, over-voltage Active mode efficiency > 84% x Input voltage protection: brown-out, brown-in, Supports high capacitance loads up to 6,000 mF unplug Low no-load power: < 100mW (at 230 V ) AC x Over-temperature protection - internal sensor 3 Applications Power Supplies for: x White Goods x Home Appliances x Industrial Control x Network Devices 18-May 2016 Evaluation Board Summary Rev. 1.0 www.dialog-semiconductor.com 1 of 7 2016 Dialog SemiconductoriW1830-EVAL Evaluation Board for 15W Dual-Output Switch-Mode Power Supply 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.
