Miniature SIP AC-DC Power Supplies

CUI Inc. Miniature SIP AC-DC Power SuppliesCUI Inc. launched their smallest AC-DC power supplies yet with the release of the PBK ultra-compact SIP series. Available in 1 W, 3 W, and 5 W families, the modules measure as small as 1.38 x 0.43 x 0.94 in. (35 x 11 x 24 mm), occupying less PCB real-estate than other conventional AC-DC power supplies, therefore allowing designers to fully maximize space where on-board AC-DC power conversion is required.
