LT3845AIFE#TRPBF Overview
Capsuled in the 16-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). 4V~60V is the supply voltage and the operating voltage of the dc control. Qualified to work in a -40°C~125°C TJ dc switcher. Switching can be done at 300kHz with this switching controller. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 16 terminations with a variety of function. The DC switcher's nominal voltage is 20V. Searching "LT3845" will return other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. DC regulator outputs 8V voltage based on test statistics. It should be noted that the dc to dc regulator only accepts 60V voltage as input voltage. DC to DC voltage regulator has the value of ALSO OPERATES IN ADJUSTABLE MODE UP TO 36V to better satisfy the requirement.
