Manufacturer Part Number
NQ40T40EGC08NKC-G
Description
Eighth-brick DC-DC Converter
Manufacturer
SYNQOR [SynQor Worldwide Headquarters]
Datasheet
Product # NQ40x40EGC08
The NiQor
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).
• 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
• Buck or buck-boost mode available
• Adjustable current limit with current monitor (C option)
• Industry standard eighth-brick pin-out configuration
• Size: 0.99" x 2.39" (25x60.6 mm)
• Total height only 0.50" (12.7 mm)
• Total weight: 1.7 oz (48 grams)
• On/Off control
• Output voltage trim permits custom voltages
• Remote Sense (S option, standard)
• Current limit trim (C option)
