LTC3851IMSE#PBF Overview


This switching controller fits most application requirements since it is packaged in a 16-TFSOP (0.118, 3.00mm Width) Exposed Pad package. The dc motor controller is adquate to generate for 1 outputs. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). 4V~38V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 250kHz~750kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a DUAL terminal on the switching converters. The 16 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. A search for "LTC3851" will reveal other relevant dc to dc converter ics. The switching converter has a total of 16 pins. Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4V. DC regulator outputs 5.5V voltage based on test statistics. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. In most cases, the dc dc regulator's output current is 25A. This information should be noted when you begin working with the component. There is a maximum frequency of 790kHz on this dc regulators.
