LTC3822EDD-1 Overview

Capsuled in the 12-WFDFN Exposed Pad package, the switching controller can be used for a wide range of applications. For outputs of 1, this dc motor controller is suitable. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 2.75V~4.5V. Qualified to work in an dc switcher with -40°C~85°C TA. With this switching controller, you can switch at 300kHz 550kHz 750kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Enable, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. Various 12 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 3.3V. Search for "LTC3822" to find other relevant dc to dc converter ics. Particularly, switching converter is a type of Switching Regulator or Controllers. 2.75V should be the minimum input voltage for the dc dc voltage regulator. It should be noted that the dc to dc regulator only accepts 4.5V voltage as input voltage.
