LTC3855EFE#TRPBF Overview
The switching controller fits in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. For outputs of 2, this dc motor controller is suitable. The pmic is packaged in Tape & Reel (TR) solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 4.5V~38V. Worked in a -40°C~85°C TA dc switcher before. Switching can be done at 250kHz~770kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. A variety of terminations with 38 of dc switching. A few of the control techniques these dc dc converter ics adapt include PHASE-SHIFT CONTROL. The nominal DC switcher's voltage input is 15V. Searching "LTC3855" will return other relevant dc to dc converter ics. Pins number 38 of switching converter in total. Switching converter is a special type of Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Statistically, the DC regulator outputs 12.5V voltage. The max frequency of the pmic can reach 850kHz. The dc to dc voltage regulator belongs to the PolyPhase? series. Channels are 1 for high-quality communication.
