Evaluation Board for 15W Dual Output Power Supplies
The iW1830-EVAL evaluation board provides a solution for development of 15W dual output power supplies for white goods, home appliances, industrial control equipment and network devices.
It uses Dialog’s iW1830 AccuSwitch™ digital off-line power supply controller IC and supplies two outputs, 12V: 1A and 5V: 0.5A, using a single primary-side controlled quasi-resonant flyback converter. Dialog’s PrimAccurate™ primary-side control in the iW1830 IC helps achieve the tight output voltage cross-regulation required by high-reliability applications, such as dishwashers, refrigerators, cooking ranges, microwaves and other multi-rail supplies, without the need for a secondary-side regulator or failure-prone optocouplers.
The iW1830 control IC eliminates the need for optocouplers and integrates a 700V power MOSFET along with Dialog’s advanced digital control and EZ-EMI®technologies to enable high efficiency power supplies with exceptional EMI performance, high reliability and a low overall BOM cost.
