LTC3855EFE#PBF Overview
As a result of 38-TFSOP (0.173, 4.40mm Width) Exposed Pad compact design, the switching controller is compatible with most applications. It is sufficient to generate 2 outputs with this dc motor controller. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~38V. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. A switching controller such as this can switch at a value of 250kHz~770kHz . dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by 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. There are a DUAL terminal on the switching converters. A variety of terminations with 38 of dc switching. The control methods that these dc dc converter ics use include PHASE-SHIFT CONTROL. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3855". The switching converter has a total of 38 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4.5V. Based on the test statistics, DC regulator outputs voltage 12.5V. DC regulator850kHz has the maximum frequency. Thare are switch converters of the PolyPhase? series. A high-quality communication requires 1 channels.
