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.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
