LM2678T-3.3/NOPB Overview


A Tube package is used in this voltage regulator to optimize performance. There are two types of analog ICs on this voltage regulator. The first type is a SWITCHING REGULATOR-type IC. Due to DC DC switching regulator's space saving design, this voltage regulator is available in a TO-220-7 (Formed Leads) package. The voltage regulator 12v has 1 outputs. On its output pins, this adjusting voltage regulator generates Fixed output. Switching regulators like this one can be mounted on the Through Hole mounting system. As long as its operating temperature is -40°C~125°C TJ, dc to dc voltage regulator should perform well. There is a switching frequency of 260kHz for this voltage regulator 12v. Voltage regulator has an input voltage (Max) of 40V. For operation, voltage regulator provides a nominal input voltage of 12V. LM2678 is a family of voltage regulators that belong to the DC/DC industry. There is a possibility that DC DC switching regulator can give voltage at 3.3V volts. During switching regulator operation, 7 pins are used. The output voltage of this voltage regulator 12v should at least be set at 3.3V volts at all times. A maximum output current of 5A A is available to meet the switching regulator operation requirements. A type of DC-DC switching regulator, belonging to the SIMPLE SWITCHER? family of voltage regulators, is what we are describing here. This DC-DC switching regulator operates from a supply voltage of 40V. Without external influences, harley voltage regulator consumes 4.2mAA of quiescent current. A dc to dc voltage regulator's dc to dc voltage regulator's minimum supply voltage of 8V V ensures reliable performance.
