Eighth-brick
DC-DC Converter
The NiQor
®
eighth-brick dc-dc converter is a non-isolated
buck-boost
regulator,
which
employs
synchronous
Non-Isolated
rectification to achieve extremely high conversion efficiency.
The High Input Voltage 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 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. These
modules are RoHS 6/6 compliant (see last page).
Operational Features
• Ultra high efficiency, up to 97% at full rated load
• Delivers up to 7.5 A of output current
• Input Voltage Range: 9 - 40 V
• Output voltage range: 0 - 40 V (negative output is possible)
• Extensive on-board input and output filtering
• No minimum load requirement means no preload
resistors required
• Buck or buck-boost mode available
• Adjustable current limit with current monitor (C option)
