DC-DC Converter
The NiQor Quarter-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 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
Quarter-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 page 11).
Non-Isolated
Operational Features
Ultra high eficiency, up to 95% at full rated load current
Delivers up to 30A of output current
Input Voltage Range: 9-40V
Output voltage range: 0-40V (negative output is possible)
Extensive on-board input and output iltering
No minimum load requirement means no preload resistors required
Buck or buck-boost versions available
Adjustable current limit with current monitor (C option)
Mechanical Features
• Industry standard quarter-brick pin-out coniguration
• Standard size: Encased - 1.54" x 2.39" (39x60.6 mm)

load current or short circuits
Input/output over-voltage protection protects load
and regulator from damaging voltages
Thermal shutdown protects converter from abnormal
environmental conditions
