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

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

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

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

50A/µsec. Oscon type low impedance caps required across output.

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

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

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

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

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

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

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

the converter.
