NXI110 Series DC/DC CONVERTERS • • • • Single output, 5 Bit Selectable (Non-Isolated) 110W Non-isolated DC/DC Converters 1 Meets VRM9.0 specification High efficiency: 84% typical @ Vin = 12V, Vout = 1.7V, Iout = 60A Multi-phase power conversion Microprocessor voltage identification input - 5 Bit VID input - 1.10V to 1.85V in 25mV steps Remote enable pin Power good signal True double ended differential remote sense Democratic current sharing, no need for master/slave configuration Up to 50A/µsec load transient no load to full load, recovery within 50µsec Overcurrent and short circuit protection Overvoltage protection with on board fuse Vertical plug-in to standard motherboard connector No minimum load requirement • • • • • • • • • 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. All specifications are typical at nominal input, full load at 25°C unless otherwise stated 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Set point accuracy Ripple and noise (See Note 1) Transient response peak dev. settling time Short circuit protection INPUT SPECIFICATIONS Input voltage range Input current UVLO turn ON voltage UVLO turn OFF voltage Start-up time Nominal line 12Vin nominal No load Remote OFF 11.0 to 13.2VDC 300mA 40mA max. 10.8V typ. 9.5V typ. 10ms Vout 20MHz bandwidth (See Note 2) See table ±0.8% 15mV pk-pk 125mV 50µs Continuous automatic recovery GENERAL SPECIFICATIONS Efficiency Switching frequency Standards Weight MTBF Mating connector ENVIRONMENTAL SPECIFICATIONS Maximum temperature shock Temperature shock Humidity Altitude Ref. to -input 5.0VDC 0.8VDC max.

Vin = 12V, Vout = 1.6V, Iout = 60A. 125mV peak deviation when slewing load from no load to full load at 50A/µsec. Oscon type low impedance caps required across output. Each phase operates at a fixed 225kHz. Effective fundamental output frequency is 900kHz / 4 phases each at 225kHz interleaved. 4 5 6 7 Recommended mating connector is AMP 1364125-1 or equivalent. From 5Hz to 20Hz, maintaining 0.02G2/Hz from 20Hz to 500Hz, all axes. Initilization level; ESD event shall cause no out-of-regulation conditions. Requires 400LFM forced air over the converter. Ensure the thermal reference point (see figure 2) is kept below 95ºC to maintain the reliability of the converter. TABLE 1 : PIN CONNECTIONS PIN NO. FUNCTION PIN NO.
