LT3481HDD#PBF Overview


For optimal performance, this voltage regulator uses the Tube package. During the development of this harley voltage regulator, 10 terminations were made. As this regulator voltage is equipped with an analog IC of the type SWITCHING REGULATOR, it is a SWITCHING REGULATOR-type voltage regulator. In order to save space, this voltage regulator is packaged in the 10-WFDFN Exposed Pad package. 1 outputs of voltage regulator are configured. The adjusting voltage regulator generates Adjustable output. This voltage regulator 12v fits the Surface Mount mounting. The operating temperature should be kept at -40°C~150°C TJ when the voltage regulator 12v is in operation. 300kHz~2.8MHz is the switching frequency of this DC-DC switching regulator. Voltage regulators like this one can operate at least with 3.6V as the dc to dc voltage regulator's minimum input voltage. As a result of the 2A 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 34V. A regulator with this 260 peak reflow temperature is essentially indestructible. For operation, voltage regulator provides a nominal input voltage of 10V. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. There is a DC/DC regulator in this family that belongs to the LT3481 family. The voltage DC DC switching regulator can produce is 20V volts. To operate the voltage regulator 12v, 10 pins are required. The output voltage for this switching regulator should be kept at 1.265V at least. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 3.8A A. An output voltage of 20V is provided by this regulator voltage. In this case, a dc to dc voltage regulator's minimum supply voltage of 3.6V volts is required to ensure reliable performance. It is able to operate from a maximum supply voltage of 36V, which is suitable for DC DC switching regulator's operation. A dc to dc voltage regulator's frequency of 2.8MHz is sufficient for maintaining high accuracy.
