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
