NiQor High Voltage DC-DC Converters

The high input voltage NiQor® family of DC-DC converters offer a unique solution for converting high-powered, variable voltages to a wide range of output voltages. The converter is a non-isolated buck-boost regulator, which employs synchronous rectification to achieve extremely high conversion efficiency. Suitable for use in IBA or to provide a regulated output voltage from a battery source or other variable voltage source. Can be configured to Buck the input voltage down or Boost the input voltage up using a single external resistor.


Product Highlights


  • Wide input voltage ranges: 9-20V, 9-40V, 9-60V and 9-90V
  • Very high efficiency achieved by non-isolated design, up to 96%
  • Smooth transition from buck to boost as input or output voltage varies
  • Current-controlled “C” version for charging batteries
  • Configuration for negative outputs or inputs
  • Input and output current limit for buck-boost version
  • Full microprocessor control of all operating parameters
  • On-board input and output noise filters for quiet operation
  • Buck-only version available for higher efficiency
  • Encased/baseplated package for protection and conductive cooling
Buck Version

     (“T” as 5th character of part number):

  • Even higher efficiency achieved from optimization for voltage reduction
  • Output voltage is always less than input voltage
  • Ideal for applications where a voltage boost isn’t needed


    • CAN/CSA C22.2 No. 60950-1:2007
    • UL 60950-1:2007
    • EN 60950-1/A12:2011

Medical Application
For medical power applications, the NQ20/40/60/90 converters are ideal for creating unique output voltages at moderate to high power levels when working with fixed-output power supplies like the SynQor ACuQor series.

As an example, the entire output power from an AQ0400MU48 power supply could be converted from 48V to 54V with a single NQ60W60QGC20 quarter-brick non-isolated convererter.

NiQor Non-Isolated DC-DC Converters

The NiQor® DC-DC converter is a non-isolated buck regulator, which employs synchronous rectification to achieve extremely high conversion efficiency. The NiQor family of converters are used predominately in DPA systems using a front end DC-DC high power brick (48Vin to low voltage bus). The non-isolated NiQor converters are then used at the point of load to create the low voltage outputs required by the design. The wide trim module can be programmed to a variety of output voltages through the use of a single external resistor.
