LTC3859ALEUHF#TRPBF Overview
Capsuled in the 38-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. For 3 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With this function, you can deal with Transistor Driver dc switching's outputs (s). A 4.5V~38V voltage is supplied to the dc control and used for operating it. Worked in a -40°C~125°C TJ dc switcher before. The switching controller is capable of switching at the 115kHz~835kHz 350kHz~535kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. 38 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. Other relevant dc to dc converter ics can be found by searching "LTC3859". Switching converter is a type of Switching Regulator or Controllers in particular. dc dc voltage regulators should have a minimum input voltage of 4.5V.
