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

acompact 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 industrywith regard to

conversion efficiency without adding unneccesarycomplexity.On-board active current

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

dynamic load conditions. 2YEAR WARRANTY
