LTC3868IUFD-1#PBF Overview


It comes in the 28-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. Tube solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 4V~24V volts and has 4V~24V supply voltage. Worked in an dc switcher with a -40°C~85°C TA rating. Using this switching controller, it is possible to switch at 105kHz~835kHz 350kHz~535kHz. Surface Mount makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. There are a QUAD terminal on the switching converters. The 28 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. LTC3868 can be searched for other relevant dc to dc converter ics. 28 pins are present on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. 4V should be the minimum input voltage for the dc dc voltage regulator. Statistically, DC regulator outputs 5.1V volts. DC regulator's maximum frequency is 850kHz. In order to ensure high-quality communication, there are 1 channels available.
