NXA66 Series

      The NXA66 non-isolated DC/DC converter aims at computing applications that require point of load power conversion. In order to meet the precise voltage and fast transient requirements of today's high performance applications,we design the  NXA66 Series ,it can reach the requirement such as workstations, file servers, desktop computers, telecommunications equipment,adapter cards, DSP and data processing. The advanced democratic current sharing technique employed by the NXA66 removes the need for cumbersome master/slave combinations. To form a convenient, low impedance interconnect scheme,the NXA66 uses gold plated edge tab fingers . This also allows system designers to easily accommodate future expansion in their systems.The NXA66 can be used in a stand-alone configuration,when employing synchronous rectification and democratic current sharing, or paralleled as a building block targeted at  achieving higher output currents or redundancy. static conditions, and transient conditions is the current sharing specifications.

      The NXA66 Series has its own characteristics.For example, Transient response from 0A to rated full load (up to 30A/s), recovery within 250s, and Democratic current sharing, no need for master/slave configuration. What's more, the Programmable output voltage, the Remote enable pin and the Power good signal makes the NXA66 Series almost  a perfect thing. It realizes true double ended differential remote sense.

      Here gives some notes of the NXA66 Series: First,in this view,  row A of the connector is on the opposite side of the unit.,and row B of the edge connector is visible. The leftmost pin is pin 50, and the rightmost pin is pin 26.Pin 1 is behind pin 50, pin 25 is behind pin 26.See below for pinout.Second,recommended mating connector is AMP 145432 or equivalent. Pin 44 is absent and is used for electrical key. AMP keying plug PN 65025-2 may be placed in the mating connector between pins 33 and 34, and between pins 17 and 18. This keying plug serves as a mechanical key.Third, rrom 5Hz to 20Hz, maintaining 0.02G2/Hz from 20Hz to 500Hz, all axes. Fourth,initilization level; ESD event shall cause no out-of-regulation conditions.
