LTC3775EUD#PBF Overview


Capsuled in the 16-WFQFN Exposed Pad package, the switching controller suits most application needs. For outputs of 1, this dc motor controller is suitable. A solid enclosure of Tube surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. A switching controller such as this can switch at a value of 250kHz~1MHz . The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the QUAD position. The 16 terminations can be used for a wide range of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. It is inputted with a DC switcher's voltage of 12V. A search for "LTC3775" will reveal other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. 4.5V should be the minimum input voltage for the dc dc voltage regulator. Statistically, the DC regulator outputs 5.2V voltage. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.6 TO 30.4V to better satisfy the need. Basically, it's a dc to dc voltage regulator from the PolyPhase? series.
