LTC3854EDDB#TRMPBF Product Details
LTC3854EDDB#TRMPBF Overview
With its 12-WFDFN Exposed Pad package, the switching controller fits the needs of most applications. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The program can handle Transistor Driver dc switching's outputs (s). 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. With this switching controller, you can switch at 400kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Soft Start. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. DUAL are the position of the terminal of the switching converters. A variety of 12 terminations are available in dc switching. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3854". Total pins of switching converter are 12. Switching converter is a special type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. According to the test statistics, DC regulator outputs 5.5V voltage. The dc to dc regulator is limited to 38V input voltage. You should note down the dc dc regulator's usual output current of 25A when you start a project. Voltage regulator dc to dc is designed to operate at 98 % duty cycle during power-ups and power-downs to ensure reliability. DC regulator440kHz has the maximum frequency. This controller contains 1 phases.
