LT3990EDD#PBF Product Details
LT3990EDD#PBF Overview
It is designed to provide optimal performance by utilizing the Tube package. There are 10 terminations in this harley voltage regulator. As this regulator voltage is equipped with an analog IC of the type SWITCHING REGULATOR, it is a SWITCHING REGULATOR-type voltage regulator. For space-saving purposes, this voltage regulator is available in the 10-WFDFN Exposed Pad package. A total of 1 outputs are configured in this voltage regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. Surface Mount-mount switching regulator. -40°C~125°C TJ should be the operating temperature when voltage regulator is operating. Voltage regulator's switching frequency reaches 210kHz~2.3MHz. The voltage regulator can be operated with a voltage as low as 4.2V as an input voltage. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 1.21V. DC DC switching regulator's 350mA output current allows for maximum design flexibility. Voltage regulators' input voltage is limited to 62V. With its peak reflow temperature of 260, this voltage regulator is essentially indestructible. To meet the operation requirements, voltage regulator is designed to provide 12V as the nominal input voltage. The regulator voltage is included in the Switching Regulator or Controllers subcategory of voltage regulators. In this case, the DC/DC regulator belongs to the family LT3990. Voltage can be produced at 3.3V volts by voltage regulator. On the basis of 25V's maximal output voltage, DC DC switching regulator can be operated easily.
