Description

Evaluation Board for 15W Single-Output Switch-Mode Power Supply.The iW1830-EVAL evalution board provides a working and tested solution for a 15W power supply based on the iW1830, a PrimAccurate™ digital off-line power supply controller IC with integrated power switch from Dialog. With an integrated 700V power MOSFET, the iW1830 provides a low total BOM cost and through the advanced digitalcontrol technology it uses, it removes the need for external secondary-side feedback components, further reducing component count and cost while improving reliability.
