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
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).
Non-Isolated
Operational Features
• Ultra high efficiency, up to 95% at full rated load
• Delivers up to 30 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)
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Size: 1.54" x 2.39" (39x60.6 mm)
• Total height only 0.515" (13.08 mm)
• Total weight: 3 oz (85 g)
Control Features
• On/Off control
• Output voltage trim permits custom voltages
• Remote Sense (S option, standard)
• Current limit trim (C option)

Protection Features
• Input under-voltage lockout protects the converter at low
input voltage conditions
• Over-current shutdown protects converter from excessive
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
Safety Features
• UL/cUL 60950-1 recognized (US & Canada)
• TUV certified to EN60950-1
• Board and plastic components meet UL94V-0
flammability requirements
