LT8705IFE#TRPBF Overview


The switching controller fits in the 38-PowerTFSOP (0.173, 4.40mm Width), 31 Leads package and is ideal for most applications. It is sufficient to generate 2 outputs with this dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. The system can process Transistor Driver dc switching's outputs (s). dc controls with 2.8V~80V voltage are supplied and operated. Suitable for a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 100kHz~400kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. The dcdc regulator features Enable, Frequency Control, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of terminations with 38 of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. Searching "LT8705" will return other relevant dc to dc converter ics. There is a particular type of Switching Regulator or Controllers in switching converter. Statistically, the DC regulator outputs 6.35V voltage. Considering the dc to dc regulator can only accept 80V input voltage, it is important to take note of this. The value of DC to DC voltage regulator is set at ALSO OPERATES IN ADJUSTABLE MODE FROM 1.3V TO 80V in order to fulfill the requirements more effectively.
