LTC3851AIMSE-1#TRPBF Overview
Capsuled in the 16-TFSOP (0.118, 3.00mm Width) Exposed Pad package, the switching controller suits most application needs. 1 outputs are supported by the dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. The supply and operating voltage of the dc control are 4V~38V. Worked in a -40°C~125°C TJ dc switcher before. There is a switch at 235kHz~750kHz that can be used with this 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. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. A variety of terminations with 16 of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "LTC3851". Switching converter is a type of Switching Regulator or Controllers in particular. dc dc voltage regulators should have a minimum input voltage of 4V. DC regulator outputs 5V voltage according to the test statistics. At most, the dc to dc regulator accepts 38V input voltage. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V. 0.05A is the greatest value switching converter outputs as current.
