LTC3873EDDB-5#TRMPBF Product Details
LTC3873EDDB-5#TRMPBF Overview
In the 8-WFDFN Exposed Pad package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. There is a Tape & Reel (TR) solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 4.1V~60V volts and has 4.1V~60V supply voltage. Suitable for working in an dc switcher that has a -40°C~85°C TA. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 5V. In addition to "LTC3873", there are other relevant dc to dc converter ics you can find. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended that the dc dc voltage regulator's minimum input voltage be 3.5V. The dc to dc regulator can only accept 9V input voltage. It is possible for this switching controller to switch at a frequency of 240kHz.
