Bus converter outputs 408W at 34A, up to 96% at 12V output
The module’s five-pin, 1/8-brick footprint is compatible with the Distributed-power Open Standards Alliance’s (DOSA) standard and has a full 36-75V telecom input range. The unit’s Hybrid Regulated Ratio (HRR) technology minimises power losses while delivering high-power conversion from a wide range of input voltages. Efficiency can be up to 96% with a 48V input and 12V output at half-load. This means the PKB4413DA cuts energy and cooling costs considerably. Tellurium copper pins give excellent thermal transport, while the module is connected to a cold-plate or heatsink via a baseplate. The thermal path from the thermally critical components to the baseplate has been carefully designed, resulting in a flat thermal profile for the key elements, along with excellent heat transfer to the heatsink or baseplate. The PKB4413DA comes in a standard eighth-brick format (58.4×22.7×13.2mm) designed to be through-hole mounted and offers 1500V(DC) I/O isolation. It also includes I/O protection and operational features, such as input under-voltage shutdown, monotonic start-up and remote control, as well as output over-voltage, over-temperature and output short-circuit protection. Its calculated MTBF is 8.5 million hours, and the module meets IEC/EN/UL60950-1 safety requirements.
