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.
