Capable of delivering 81 A, and meeting the exceptional transient response requirements of these loads, the converter comes in a versatile, PCB-pluggable form. Artesyn utilizes advanced circuit techniques, component selection and state-of-the-art thermal packaging, to deliver reliable high power density. Multi-phase power conversion provides industry-leading conversion efficiency without adding unneccesary complexity, and NXI100 meets the precise regulation specifications of VRM9.0/9.1 without expensive external components. An active circuit guarantees the current sharing specification is met during static or dynamic loading conditions.
