Luso Electronics Distribution now has available SynQor’s high-input-voltage NiQor family of DC-DC converters for a range of industrial and telecom applications. Included within the range is a product that is ideally suited to use in HEVs (Hybrid Electric Vehicles) or in a myriad of portable battery-charging applications such as fuel cell or solar-energy based power generators.

The SynQor NiQor family of DC-DC converters offers an industry-leading solution for converting high powered and variable voltages - input voltages from 9 to 90V - to a wide range of output voltages. The converter series is a non-isolated buck-boost regulator that employs synchronous rectification to achieve extremely high-conversion efficiency.

Suitable for use in Intermediate Bus Architecture (IBA) based telecom systems, or to provide a regulated output voltage from a battery source or other variable voltage sources, the converter can also be configured to buck the input voltage down or boost the input voltage up using a single external resistor.

Particularly of note within the range is a current-controlled 'C' version. The device's output current limit is externally controlled for constant-current charging, the current being set by either an external resistor or an active circuit. Other features of the 'C' version include: current analogue signal provided for instrumentation and control functions; an 'ideal diode' output stage with zero back-drive current prevents battery discharge when not charging; independent control of the output voltage set-point via the trim pin; and a smooth transition between current and voltage modes as power needs change across the charging cycle.
