LTC3859ALMPFE#TRPBF Overview
As a result of 38-TFSOP (0.173, 4.40mm Width) Exposed Pad compact design, the switching controller is compatible with most applications. There is enough capacity in the dc motor controller to generate the output for the 3 input. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc control's supply and operating voltages are 4.5V~38V. Workable in an dc switcher where -55°C~150°C TJ is the -55°C~150°C TJrm. Switching can be done at 115kHz~835kHz 350kHz~535kHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 38 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. LTC3859 can be searched for other relevant dc to dc converter ics. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V.
