1 / 7 page iW1830-EVAL1 Evaluation Board for 15W Single-Output Switch-Mode Power Supply Rev. 1.0 Evaluation Board Summary © 2016 Dialog Semiconductor www.dialog-semiconductor.com 1 of 7 18-May-2016 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 ● Wide input voltage range: 90VAC to 264VAC ● Output voltage: 5V ● Output current: 3A ● Total output power: 15W max. ● Integrated 700V MOSFET ● Active mode efficiency > 82% ● Supports high capacitance loads up to 6,000mF ● Low no-load power: < 50mW (at 230 VAC) 3 Applications ● Power Supplies for: x White Goods x Home Appliances x Industrial Control x Network Devices ● EZ-EMI® technology: excellent EMI performance with a minimum of EMI filtering components ● Quasi-resonant operation ● Low component count and small PCB footprint ● iW1830 IC protections: x Output short-circuit, over-current, over-voltage x Input voltage protection: brown-out, brown-in, unplug x Over-temperature protection - internal sensor |
