LT3640EUFD#PBF Product Details
LT3640EUFD#PBF Overview
Using the Tube package, this voltage regulator optimizes the performance of the voltage regulator 12v. In this voltage regulator, 28 terminations are present. As this regulator voltage is equipped with an analog IC of the type DUAL SWITCHING CONTROLLER, it is a DUAL SWITCHING CONTROLLER-type voltage regulator. In order to save space, this voltage regulator is packaged in the 28-WFQFN Exposed Pad package. 2 outputs have been configured in the voltage regulator 12v. On its output pins, this adjusting voltage regulator generates Adjustable output. This voltage regulator 12v fits the Surface Mount mounting. As long as its operating temperature is -40°C~125°C TJ, dc to dc voltage regulator should perform well. 500kHz~2MHz is the switching frequency of this DC-DC switching regulator. The voltage regulator can be operated with a voltage as low as 2.5V as an input voltage. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.6V 1.265V. As a result of the 1.1A 1.3A output current, voltage regulator offers maximum flexibility in design. As far as the voltage input is concerned, DC DC switching regulator can accept up to 35V. Due to its 260 high peak reflow temperature, this voltage regulator 12v is virtually indestructible. Voltage regulator is designed to provide a nominal input voltage of 12V to meet the operation requirements. There is a subcategory of this regulator voltage called Switching Regulator or Controllers. LT3640 is a family of voltage regulators that belong to the DC/DC industry. A voltage of 3.3V volts can be generated by DC DC switching regulator. There are 28 pins that are used for the operation of the voltage regulator 12v. By using the 33.97V's maximal output voltage, adjusting voltage regulator can operate easily. Switching regulators with the PFM CONTROL TECHNIQUE ALSO POSSIBLE feature are more efficient and stable.
