The Distributed-power Open Standards Alliance (DOSA), a global association dedicated to furthering compatibility and standardization in the dc-dc board mounted power conversion market, recently approved specification standards for the "Third Generation, High Density, Non-Isolated PICO converter" for the PICO (12 x 12mm) format.
The third generation standard is based on the addition of new interconnects to enable new features and digital communication while maintaining the integrity of the second generation connections and dimensions. This allows the highest design flexibility with the opportunity to use previous generation products on the new footprint, or alternatively use new generation products with existing circuit board footprints. While the standard establishes the new connectivity for digital communication, it is not restricted to digital POLs. The standard applies to both analog and digital non-isolated POLs and creates allowances for additional new features such as differential remote sense and synchronization.
