LTC3855EUJ#TRPBF Overview

This switching controller fits most application requirements since it is packaged in a 40-WFQFN Exposed Pad package. It is sufficient to generate 2 outputs with this dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 4.5V~38V. A -40°C~85°C TA dc switcher is not a problem. There is a switch at 250kHz~770kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of 40 terminations are available in dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PHASE-SHIFT CONTROL. DC switcher's input voltageis 15V volts. Search for "LTC3855" to find other relevant dc to dc converter ics. The switching converter has a total of 40 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. Statistically, DC regulator outputs 12.5V volts. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. 850kHz is the maximum frequency of this dc regulators. The dc to dc voltage regulator is from the PolyPhase? series. There are 1 channels for high-quality communication.
