LT3640EFE#TRPBF Product Details
LT3640EFE#TRPBF Overview
For optimal performance, this voltage regulator makes use of the Tape & Reel (TR) package. In this voltage regulator, there are a total of 28 terminations. There is one type of analog IC that this voltage regulator is equipped with, and that is the DUAL SWITCHING CONTROLLER type. In order to save space, this harley voltage regulator is available in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package. There are 2 outputs configured on this voltage regulator 12v. There are output pins on this DC DC switching regulator that generate Adjustable 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 500kHz~2MHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 2.5V. As a result, the output voltage of the voltage regulator 12v (Min/Fixed) is 0.6V 1.265V. It features maximum design flexibility due to dc to dc voltage regulator's 1.1A 1.3A output current. Voltage regulator has a maximum input voltage of 35V. 260 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 12V. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. The LT3640 family of DC/DC regulators includes this DC/DC regulator. Based on the maximal adjusting voltage regulator's output voltage of 33.97V, adjusting voltage regulator can be operated easily. This switching regulator is more efficient and stable due to the PFM CONTROL TECHNIQUE ALSO POSSIBLE feature.
