LTC3859EUHF#PBF Overview
In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. For 3 outputs, the dc motor controller is appropriate. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~38V. Worked in a -40°C~125°C TJ dc switcher before. Switching can be done at 115kHz~835kHz 350kHz~535kHz with this switching controller. dc dc regulators can be carried out with Surface Mount. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. QUAD are the position of the terminal of the switching converters. 38 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". There are a total of 38 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.5V. According to the test statistics, DC regulator outputs 60V voltage. normally, the dc dc regulator's output current is 25A, which you should keep in mind when starting a project. It is estimated that this dc regulatorhas a maximum frequency of 850kHz. Channels are 1 for high-quality communication.
