LTC3855EFE#PBF Product Details

LTC3855EFE#PBF Overview


Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 4.5V~38V. Qualified to work in a -40°C~85°C TA dc switcher. This switching controller can switch at 250kHz~770kHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking for efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 38 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PHASE-SHIFT CONTROL. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "LTC3855". Switching converter has a total of 38 pins. Switching converter is a type of Switching Regulator or Controllers in particular. The minimum input voltage of the dc dc voltage regulator should be 4.5V. According to the test statistics, DC regulator outputs 12.5V voltage. The max frequency of the pmic can reach 850kHz. It belongs to the PolyPhase® series of dc to dc voltage regulator. For high-quality communication, there are 1 channels.
