NXI110-12P1V8C - Emerson - Product.Network

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

Notes

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.
