LTC3855IFE#TRPBF Overview
It comes in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, so switching controller can be used for most applications. For 2 outputs, the dc motor controller is appropriate. An enclosure of Tape & Reel (TR) is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4.5V~38V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~125°C TJ. The switching controller can be switched at 250kHz~770kHz. The Surface Mount allows it to be used for dc dc regulator in general. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. Searching "LTC3855" will return other relevant dc to dc converter ics. 38 pins are present on switching converter. It is estimated that this dc regulatorhas a maximum frequency of 850kHz. At -40°C and above, dc regulator should be kept. DC regulator should run at a temperature 125°C higher than 125°C. Basically, it's a dc to dc voltage regulator from the PolyPhase? series. Its supplier dc dc controller package would be 38-TSSOP-EP. There are 1 channels for high-quality communication.
