LTC3859IUHF#PBF Overview
In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. There is enough capacity in the dc motor controller to generate the output for the 3 input. Tube solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 115kHz~835kHz 350kHz~535kHz. The Surface Mount value makes it suitable for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . There are many different types of terminations for 38. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". There are 38 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. 4.5V should be the minimum input voltage for the dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 60V. This dc regulatorhas a max frequency of 850kHz. In order to ensure high-quality communication, there are 1 channels available.
