The NXI110 non-isolated dc-dc converters are designed to meet the exceptionally fast transient response

requirements of today’s microprocessors and fast switching logic in a compact size at a very affordable price.

Advanced Circuit techniques, component selection and placement optimization, state-of-the-art thermal packaging,

and Surface Mount Technologies provide a high power density, highly reliable, and very precise voltage regulation

system for advanced microprocessors. Multi-phase power conversion techniques allow the NXI converters to lead

the industry with regard to conversion efficiency without adding unneccesary complexity. VRM9.0 specification

compliant without the need for expensive external components. On board active current sharing circuit guarantees

the current sharing specification is met both during both static and dynamic load conditions.

NNootteess

115 mV pk-pk ripple with no external output filtering.

Vin = 12 V, Vout = 1.6 V, Iout = 60 A.

2125 mV peak deviation when slewing load from no load to full load at 50

A/µsec. Oscon type low impedance caps required across output.

3Each phase operates at a fixed 225 kHz. Effective fundamental output

frequency is 900 kHz / 4 phases each at 225 kHz interleaved.

4Recommended mating connector is AMP 1364125-1 or equivalent.

5From 5 Hz to 20 Hz, maintaining 0.02 G2/Hz from 20 Hz to 500 Hz, all axes.

6Initilization level; ESD event shall cause no out-of-regulation conditions.

7Requires 400 LFM forced air over the converter. Ensure the thermal

reference point (see figure 2) is kept below 95 ºC to maintain the reliability

of the converter.

8The ‘Y’ suffix indicates that these parts are TSE RoHS 5/6 (non Pb-free)

compliant.

9NOTICE: Some models do not support all options. Please contact your
