1 of 7 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 fyback 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 effciency and help meet emi standards. this quasi-resonant operation and dialogs ez-emi ? technology enable excellent emi performance with minimal external fltering. proprietary control technology allows high effciency across a broad range of loads, which enables the iw1830 to meet stringent international standards for power supply effciency. 2 features wide input voltage range: 90v ac to 264v ac output voltages: 12v and 5v output current: 12v - 1a, 5v - 500ma total output power: 15w max. integrated 700v mosfet active mode effciency > 84% supports high capacitance loads up to 6,000 m f low no-load power: < 100mw (at 230 v ac ) 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 external emi fltering 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 iw1830-eval evaluation board for 15w dual-output switch-mode power supply rev. 1.0 evaluation board summary ? 2016 dialog semiconductor www.dialog-semiconductor.com 18-may 2016
