| Embedded Power for Business-Critical Continuity NXI150 Series Single output Rev.03.28.07 nxi150 1 of 4 Input Voltage: 11 - 12.6VDC # of Outputs: Single Special Features * 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/s 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 * 2 year warranty 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.
