LTC3822EDD-1#TRPBF Overview


It comes in the 12-WFDFN Exposed Pad package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 1 outputs. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. 2.75V~4.5V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -40°C~85°C TA rating. A switching controller such as this can switch at a value of 300kHz 550kHz 750kHz . The Surface Mount allows it to be used for dc dc regulator in general. To ensure efficient switching, this dcdc regulator features a Enable, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of 12 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 3.3V. Searching "LTC3822" will return other relevant dc to dc converter ics. The switching converter has a total of 12 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. 2.75V should be the minimum input voltage for the dc dc voltage regulator. Statistically, the DC regulator outputs 4.45V voltage. It should be noted that the dc to dc regulator only accepts 4.5V voltage as input voltage. The dc dc regulator's usual output current is 20A, which should be noted down when you start a project. DC regulators have a maximum frequency of 850kHz.
