LTC3855IFE#PBF Overview
Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller suits most application needs. For 2 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Qualified to work in a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 250kHz~770kHz. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. Various 38 terminations. This dc dc converter ic uses a variety of control techniques, including PHASE-SHIFT CONTROL. DC switcher's input voltageis 15V volts. LTC3855 can be used to locate other relevant dc to dc converter ics. Switching converter has a total of 38 pins. The type is a particular Switching Regulator or Controllers of switching converter. This dc dc voltage regulator should be powered by a voltage of 4.5V. DC regulator has a maximum frequency of 850kHz. The dc to dc voltage regulator is from the PolyPhase? series. Communication on 1 channels is high-quality.
