LTC3874IUFD#PBF Overview
As a result of 28-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 4.5V~38V. Worked in an dc switcher with a -40°C~125°C TJ rating. A switching controller such as this can switch at a value of 250kHz~1MHz . The Surface Mount allows it to be used for dc dc regulator in general. Current Limit, Enable, Frequency Control, Phase Control provides dcdc regulator efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. QUAD are the position of the terminal of the switching converters. The 28 terminations can be used for a wide range of dc switching. DC switcher's voltage input of 12V. LTC3874 can be used to locate other relevant dc to dc converter ics. There are 28 pins on switching converter. This dc dc voltage regulator should be powered by a voltage of 4.5V. The dc to dc regulator can only accept 38V input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 25A. This value is OUTPUT VOLTAGE RANGE UP TO 5.5 VOLT so that DC to DC voltage regulator better serves the purpose. Thare are switch converters of the PolyPhase? series.
