iW1818-EVAL Evaluation Board for 10W Single Output Power Supplies 
The iW1818-EVAL evaluation board provides a solution for development of 10W single output power supplies for white goods, home appliances, industrial control equipment and network devices. 
It uses Dialog’s iW1818 AccuSwitch™ digital off-line power supply controller IC and supplies a 5V: 2A regulated output using a primary-side controlled, quasi-resonant flyback converter. 
The iW1818 PrimAccurate™ primary-side control IC eliminates the need for optocouplers and integrates an 800V power BJT 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.
