LM2678SX-3.3 Product Details

LM2678SX-3.3 Overview


For optimal performance, this voltage regulator makes use of the Tape & Reel (TR) package. In this voltage regulator, there are a total of 7 terminations. There is one type of analog IC that this voltage regulator is equipped with, and that is the SWITCHING REGULATOR type. In order to save space, this harley voltage regulator is available in the TO-263-8, D2Pak (7 Leads + Tab), TO-263CA package. There are 1 outputs configured on this voltage regulator 12v. There are output pins on this DC DC switching regulator that generate Fixed output. Surface Mount-mounting is compatible with this switching regulator. The operating temperature should be kept at -40°C~125°C TJ when the voltage regulator 12v is in operation. This DC-DC switching regulator has a switching frequency of 260kHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 8V. As a result, the output voltage of the voltage regulator 12v (Min/Fixed) is 3.3V. 235 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. The LM2678 family of DC/DC regulators includes this DC/DC regulator. The voltage DC DC switching regulator can produce is 3.3V volts. There are 7 pins that are used for the operation of the voltage regulator 12v. There should be at least a 3.3V volt output voltage for this switching regulator in order to make it work properly. The maximum output current reaches 5A A to meet the switching regulator operation requirements. As a member of the SIMPLE SWITCHER® family of DC/DC regulators, this part is prominent in many specifications. 40V is the supply voltage for this DC-DC switching regulator. Despite external influences, voltage regulator consumes 4.2mA A of quiescent current.
