CUI has expanded their open-frame AC-DC line with a family of ultra-compact modules in a SIP package. The 1 W, 3 W, and 5 W configurations of the PBO series measure as small as 35 x 11 x 18 mm (1.38 x 0.43 x 0.71 in), allowing them to occupy less board real-estate than other power solutions. The models are also available in low-profile, right-angle versions, making them ideal for applications where vertical board space is at a premium.
