| NXI100 Series DC-DC CONVERTERS Single output 81 A Non-Isolated DC-DC Converters NEW Product 1 * Designed for VRM9.0 and VRM9.1 specification * Low profile: 1.15 inches including mating connector * Microprocessor voltage identification input - 5 Bit VID input - 1.10 Vdc to 1.85 Vdc in 25 mV steps * Up to 50 A/s load transient no load to full load, recovery within 50 s * Democratic current sharing, no need for master/slave configuration * High efficiency: 87% typical @ Vin = 12 V, Vout = 1.5 V, Iout = 60 A * Available RoHS compliant The NXI100 non-isolated dc-dc converter simplifies the application of Intel Xeon(TM) or Pentium(R)4 processors by providing a purpose-designed, point-of-load, power management solution for low-profile applications. Capable of delivering 81 A, and meeting the exceptional transient response requirements of these loads, the converter comes in a versatile, PCBpluggable 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. All specifications are typical at nominal input, full load at 25 C unless otherwise stated 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Output setpoint accuracy Vout Ripple and noise (See Note 1) Transient response peak dev. settling time Short circuit protection INPUT SPECIFICATIONS Input voltage range Input current 12 Vin nominal Operating No load OUTEN low 11-12.6 Vdc 13.6 A 300 mA 40 mA max. 9.9 V typ. 8.5 V typ.
