DC-DC CONVERTERS 81 A DC-DC Non-Isolated Converters

NEW Product

• Meets VRM9.1 specification

• 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

• Democratic current sharing, no need for

master/slave configuration

• Remote sense for improved load regulation

• Vertical plug-in to standard motherboard connector with

or without retention latch

• Available RoHS compliant

The NXI150 non-isolated dc-dc converter is 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. On-board active current

sharing circuit guarantees the current sharing specification is met during static and

dynamic load conditions.
