NXI150 Series
Single output
DC-DC CONVERTERS 81 A DC-DC Non-Isolated Converters
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.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
