| NXI150 Series DC-DC CONVERTERS Single output 81 A DC-DC Non-Isolated Converters NEW Product 1 * 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 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. All specifications are typical at nominal input, full load at 25 C unless otherwise stated 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Output setpoint accuracy Vout Ripple and noise (See Notes 1 and 2) Transient response peak dev. settling time Short-circuit protection 20 MHz bandwidth See Note 3 1.10-1.85 Vdc 0.8% 15 mV pk-pk 50 mV 25 s Continuous current limit, foldback automatic recovery GENERAL CHARACTERISTICS Efficiency Switching frequency Standards Weight MTBF Mating connector ENVIRONMENTAL SPECIFICATIONS Maximum temperature shock Temperature shock Humidity (Non-condensing) Altitude Shock Operating Operating Non-operating Operating Storage Operating Storage Operational and non-operational Operational and non-operational 5 C/10 min. 10 C/hour 20 C/hour 85% RH 95% RH 10,000 feet max. 50,000 feet max. 50 G 11 ms, half sine wave 0.02 G2/Hz max.
