LM2678SX-3.3/NOPB Overview


It is designed to provide optimal performance by utilizing the Tape & Reel (TR) package. As you can see, this harley voltage regulator contains 7 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. There is a TO-263-8, D2Pak (7 Leads + Tab), TO-263CA package available for this voltage regulator, as DC DC switching regulator is space-saving. There are 1 outputs configured on the voltage regulator. There are output pins on this DC DC switching regulator that generate Fixed output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. As long as its operating temperature is -40°C~125°C TJ, dc to dc voltage regulator should perform well. This voltage regulator 12v reaches a switching frequency of 260kHz. This voltage regulator is able to operate with the minimal input voltage of 8V. As a result, the output voltage of the voltage regulator 12v (Min/Fixed) is 3.3V. As a result of the 245 peak reflow temperature, this regulator is essentially indestructible. DC/DC regulators such as this one belong to the LM2678 family of products. At 3.3V volts, voltage regulator can provide voltage. The switching regulator operation of the system is controlled by 7 pins. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 5A A. The switching DC-DC regulator belongs to the SIMPLE SWITCHER? family of electronic voltage regulator 12vs. With 40V as the supply voltage, this DC-DC switching regulator will operate. There is no external influence on harley voltage regulator as it consumes 4.2mA A of quiescent current. The 8V V dc to dc voltage regulator's minimum supply voltage ensures reliable performance.
