Overview
NXA66 Series DC-DC CONVERTERS Single output (Non-Isolated) 66 W Non-isolated DC-DC Converters 1 • Transient response from 0 A to rated full load (up to 30 A/µs), recovery within 250 µs • Democratic current sharing, no need for master/slave configuration • Programmable output voltage • Remote enable pin • Power good signal • True double ended differential remote sense • Available RoHS compliant 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.
