LM2678SD-3.3 Product Details

LM2678SD-3.3 Overview


It uses the Tape & Reel (TR) package in order to optimize the performance of this voltage regulator. In this voltage regulator, 14 terminations are present. A SWITCHING REGULATOR analog IC is used in this voltage regulator 12v, which is the type of analog IC that this voltage regulator 12v is equipped with. The space-saving 14-VDFN Exposed Pad package is available for this voltage regulator. In this case, DC DC switching regulator has 1 outputs configured to it. ICs such as this voltage regulator are capable of generating Fixed outputs through their output pins. There is a switching regulator that is compatible with the Surface Mount mounting. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~125°C TJ. In this voltage regulator 12v, the switching frequency is 260kHz. Voltage regulators like this one can operate at least with 8V as the dc to dc voltage regulator's minimum input voltage. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 3.3V. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. LM2678 is a family of voltage regulators that belong to the DC/DC industry. Voltage can be produced at 3.3V volts by voltage regulator. In order to operate voltage regulator, there are 14 pins that must be connected. Ideally this switch regulator should have an output voltage of about 3.3V at the very least. A maximum output current of 5A A is available to meet the switching regulator operation requirements. Known as a switching DC-DC regulator, this voltage regulator belongs to the SIMPLE SWITCHER? family. With 40V as the supply voltage, this DC-DC switching regulator will operate. An external factor does not affect harley voltage regulator's ability to consume 4.2mA A of quiescent current.
