| NXA66 Series Single output Non-Isolated DC/DC CONVERTERS 66W Non-isolated DC/DC Converters • Transient response from 0A to rated full load up to 30A/µs , recovery within 250µs • Democratic current sharing, no need for master/slave configuration • Programmable output voltage • Remote enable pin • Power good signal • True double ended differential remote sense The NXA66 non-isolated DC/DC converter is targeted at computing applications that require point of load power conversion. The NXA66 is designed to meet the precise voltage and fast transient requirements of today’s high performance applications such as workstations, file servers, desktop computers, telecommunications equipment, adapter cards, DSP and data processing. Employing synchronous rectification and democratic current sharing, the NXA66 can be used in a stand-alone configuration, or paralleled as a building block to achieve higher output currents or redundancy. The current sharing specifications are met during static conditions, and transient conditions. The advanced democratic current sharing technique employed by the NXA66 removes the need for cumbersome master/slave combinations. The NXA66 uses gold plated edge tab fingers for a convenient, low impedance interconnect scheme. This also allows system designers to easily accommodate future expansion in their systems. All specifications are typical at nominal input, full load at 25°C unless otherwise stated 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Vout programmable to 2V5 or 3V3 Total error band 3V3 output 2V5 output Ripple and noise 20MHz bandwidth 150mV pk-pk max.
