LTC3856EFE Overview


As a result of 38-TFSOP (0.173, 4.40mm Width) Exposed Pad compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. The pmic is packaged in Tube solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 4.5V~38V voltage are supplied and operated. Worked in a -40°C~125°C TJ dc switcher before. There is a switch at 250kHz~770kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at DUAL. A variety of dc switching's functions can be performed on 38 terminations. The DC switcher's nominal voltage is 15V. LTC3856 can be searched for other relevant dc to dc converter ics. In particular, switching converter belongs to the Switching Regulator or Controllers family. dc dc voltage regulators should have a minimum input voltage of 4.5V. This dc to dc regulator accepts only 38V input voltage at most. As a result, DC to DC voltage regulator has a value of ALSO OPERATES AS LDO REGULATOR, OPERATES IN ADJUSTABLE MODE FROM 0.6 TO 5V so that the need can be met more directly. Current is output to the greatest value of 0.1A. Basically, it's a dc to dc voltage regulator from the PolyPhase? series.
