LTC3809EDD-1#PBF Overview


In the 10-WFDFN Exposed Pad package, the switching controller meets most application requirements. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tube solid enclosures. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control has a supply voltage and operating voltage of 2.75V~9.8V. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. The switching controller can be switched at 550kHz. dc dc regulators can be carried out with Surface Mount. The dcdc regulator features Enable, Soft Start, Tracking for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . Different dc switching's functions can be applied to 10 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 4.2V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC3809". There are 10 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 9.8V voltage according to the test statistics. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. 750kHz is the frequency of the switching controller. The dc switcher's maximum input voltage is 9.8V; users must limit it accordingly. An output current greater than 1A cannot be provided by the dc switcher. At its maximum output, the switching converter can provide 9.8V volts. A voltage controller's lowest output voltage cannot be less than 600mV.
