LTC3869IUFD#PBF Overview


As a result of 28-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. 2 outputs can be generated with the dc motor controller. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). A 4V~38V voltage is supplied to the dc control and used for operating it. Suitable for working in an dc switcher that has a -40°C~125°C TJ. With this switching controller, you can switch at 250kHz~780kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . The 28 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics can be found by searching "LTC3869". 28 pins are present on switching converter. This dc dc voltage regulator should be powered by a voltage of 4V. According to the test statistics, DC regulator outputs 12.5V voltage. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. In most cases, the dc dc regulator's output current is 25A. This information should be noted when you begin working with the component. There is a maximum frequency of 850kHz on this dc regulators. Communication with high quality requires 1 channels.
