Power Modules Go Digital

Ericsson’s second digital-power Advanced Bus Converter platform, the FRIDA II platform, is intended for use with board-mounted DC/DC power modules in telecom and datacom applications. It is built around the capabilities of the 32-bit ARM7TDMI-S microprocessor core and integrates hardware and firmware optimized to guarantee the highest efficiency at any point of operation. The platform offers a tightly regulated output voltage of 2% across an operational range from 36V to 75V. FRIDA II also includes proprietary firmware to integrate complex scenarios and the challenges faced by DC/DC board-mounted power supplies in telecom and datacom applications such as in ATCA or AdvancedTCA or remote telecom equipment that is connected to an unstable power grid.
