NiQor High Voltage DC/DC Converters
    High input voltage, non-isolated brick dc-dc converters
NiQor Series Hi-Voltage Non-Isolated DC-DC Converters The high input voltage NiQor® family of dc-dc converters offer a unique solution for converting high-powered, varible 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
