Belleta® iPB Series DC/DC Power Modules

48V Input, 10A Output

Surface Mount PicoBrick

The Belleta Series offers a 35W PicoBrick power module in the industry’s smallest 10A footprint that is 33% smaller than an industry standard eighth brick and power pin compatible with an existing industry standard footprint. The Belleta Series eliminates the need to use highly derated eighth or quarter brick power modules, thereby optimizing board space utilization and cost. As with other modules in the Belleta series, a low component count results in a low cost, high performance design. The low weight, surface mount design is well suited for almost any manufacturing environment.
