LTC3854IDDB#TRMPBF Overview


Capsuled in the 12-WFDFN Exposed Pad package, the switching controller suits most application needs. An enclosure of Tape & Reel (TR) is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. Work well in dc switchers with a -40°C~85°C TA. It can switch at 400kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. The dcdc regulator features Enable, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . Different dc switching's functions can be applied to 12 terminations. The DC switcher's nominal voltage is 15V. You can find other relevant dc to dc converter ics by searching "LTC3854". In total, switching converter has 12 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. dc dc voltage regulators should have a minimum input voltage of 4.5V. According to the test statistics, DC regulator outputs 5.5V voltage. Considering the dc to dc regulator can only accept 38V input voltage, it is important to take note of this. A starting point for a project is to note down the dc dc regulator's usual output current, which is 25A. The duty cycle of the voltage regulator dc to dc can be set to 98 % on power-up or power-down to ensure reliability. DC regulator has a maximum frequency of 440kHz. The phase of this controller is 1.
