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 offline 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 ●● Wide input voltage range: 90VAC to 264VAC ●● Output voltages: 12V and 5V ●● Output current: 12V - 1A, 5V - 500mA ●● Total output power: 15W max. ●● Integrated 700V MOSFET ●● EZ-EMI® technology: excellent EMI performance with a minimum of external EMI filtering components ●● Quasi-resonant operation ●● Low component count and small PCB footprint ●● iW1830 IC protections: xx Output short-circuit, over-current, over-voltage ●● Active mode efficiency > 84% ●● Supports high capacitance loads up to 6,000mF xx Input voltage protection: brown-out, brown-in, unplug ●● Low no-load power: < 100mW (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 Evaluation Board Summary www.dialog-semiconductor.com Rev. 1.0 1 of 7 18-May 2016 © 2016 Dialog Semiconductor iW1830-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.
