NB639DL-LF-P Product Details

NB639DL-LF-P Overview

For optimal performance, this voltage regulator makes use of the Tape & Reel (TR) package. For space-saving purposes, this voltage regulator is available in the 20-PowerVFQFN package. There are 1 outputs configured on this voltage regulator 12v. As you can see, this DC DC switching regulator generates Adjustable output on its output pins. This switching regulator is designed to fit the Surface Mount mounting system. The operating temperature should be kept at -40°C~125°C TJ when the voltage regulator 12v is in operation. Voltage regulators like this one can operate at least with 4.5V as the dc to dc voltage regulator's minimum input voltage. The output voltage (Min/Fixed) of this voltage regulator 12v is 0.8V. Featuring a 8A output current, dc to dc voltage regulator offers maximum design flexibility. The maximum input voltage of voltage regulator is 28V. Voltage can be produced at 13V volts by voltage regulator. The output voltage for this switching regulator should be kept at 800mV at least. By using the 13V's maximal output voltage, adjusting voltage regulator can operate easily. It provides the adjusting voltage regulator's maximal output voltage of 13V. By requiring a minimum voltage of 4.5VV, adjusting voltage regulator reliable performance is guaranteed. A high maximum operating temperature 125°C ensures stable operation of switching regulator. To ensure reliability, harley voltage regulator operates at a minimum operating temperature of -40°C. The dc to dc voltage regulator's minimum input voltage for this voltage regulator 12v is 4.5V. Designed to sustain a maximum input voltage of 28V, this DC-DC switching regulator maintains a maximum output voltage of DC.
