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, 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.

Notes
1
15 mV pk-pk ripple 8 x 560 μF/4 V OSCON and 10 x 4.7 μF/6.3 V MLCC’st on the output. Vin = 12 V, Vout = 1.5 V, Iout =
60 A.
2 125 mV peak deviation when slewing load from no load to full load at 50 A/μs. Oscon type low impedance caps required
across output.
3 Each phase operates at a fixed 330 kHz. Effective fundamental output
frequency is 990 kHz / 3 phases each at 330 kHz interleaved.
4 Recommended mating connector is AMP 1364125-1 or equivalent.
5 From 5 Hz to 20 Hz, maintaining 0.02 G2/Hz from 20 Hz to 500 Hz, all axes.
6 Test performed in end use equipment.
7 Refer to thermal de-rating curves found in the long form datasheet.
8 VID code lower than 1.25 V, use 5 A as minimum load.
9 The ‘Y’ suffix indicates that these parts are TSE RoHS 5/6 (non Pb-free) compliant.
10 NOTICE: Some models do not support all options. Please contact your local Artesyn representative or use the on-line
model number search tool at http://www.artesyn.com/powergroup/products.htm to find a suitable alternative.
