LT3990EDD#PBF Overview


There is an optimized performance in this voltage regulator because it utilizes the Tube package. Throughout this voltage regulator, there are 10 terminations. A SWITCHING REGULATOR type of analog IC is equipped with this regulator voltage, which is the type of analog IC that is used in it. In order to save space, this voltage regulator is packaged in the 10-WFDFN Exposed Pad package. 1 outputs of voltage regulator are configured. DC DC switching regulators like this one generate Adjustable outputs on their output pins to handle the power management. This voltage regulator 12v fits the Surface Mount mounting. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. The switching frequency of this DC-DC switching regulator reaches 210kHz~2.3MHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 4.2V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 1.21V. It features maximum design flexibility due to dc to dc voltage regulator's 350mA output current. Voltage regulator has an input voltage (Max) of 62V. The peak reflow temperature of this regulator amounts to 260 to be essentially indestructible. To meet the switching regulator operation requirements, a nominal input voltage of 12V is provided. The regulator voltage is included in the Switching Regulator or Controllers subcategory of voltage regulators. There is a DC/DC regulator in this family that belongs to the LT3990 family. There is a possibility that DC DC switching regulator can give voltage at 3.3V volts. Based on the maximal adjusting voltage regulator's output voltage of 25V, adjusting voltage regulator can be operated easily.
