LTC3856IFE Product Details

LTC3856IFE Overview


Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 4.5V~38V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 250kHz~770kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 38 terminations. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "LTC3856". Specially, switching converter corresponds to type Switching Regulator or Controllers. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. A maximum voltage of 38V is accepted by the dc to dc regulator as an input voltage. The value of DC to DC voltage regulator is set at ALSO OPERATES AS LDO REGULATOR, OPERATES IN ADJUSTABLE MODE FROM 0.6 TO 5V in order to fulfill the requirements more effectively. A maximum value of 0.1A is output for current. Basically, it's a dc to dc voltage regulator from the PolyPhase® series.
