NXI100 Series Single output DC-DC CONVERTERS 81 A Non-Isolated DC-DC Converters 1 NEW Product • 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/µs load transient no load to full load, recovery within 50 µs • 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®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. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25 °C unless otherwise stated OUTPUT SPECIFICATIONS Voltage adjustability GENERAL CHARACTERISTICS See table Output setpoint accuracy Vout Ripple and noise (See Note 1) 20 MHz bandwidth Transient response peak dev. settling time (See Note 2) Efficiency 1.5 V output @ 60 A 1.7 V output @ 60 A Switching frequency Fixed (See Note 3) ±0.8% 15 mV pk-pk Standards Short circuit protection 50 mV 25 µs Continuous current automatic recovery 990 kHz 94V-0 flammability rating Weight MTBF 87% 87% 40 g (1.41 oz) Telcordia SR-332 Mating connector 850,000 hours (See Note 4) INPUT SPECIFICATIONS Input voltage range 12 Vin nominal 11-12.6 Vdc Input current Operating No load OUTEN low 13.6 A 300 mA 40 mA max.
