The MCOTS NiQor® half-brick DC-DC converter is a non-isolated buck-boost regulator which employs synchronous rectification to achieve extremely high conversion efficiency. The High Input Voltage MCOTS NiQor Brick family of converters can be used in traditional DPA (distributed power architecture) systems or provide a regulated output voltage from a battery source or other variable voltage source. The MCOTS NiQor Brick family can be configured to Buck the input voltage down to a lower voltage or Boost the input voltage up to a higher voltage using a single external resistor.
