LTC3728LEUH-1#PBF Overview
With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc control's supply and operating voltages are 4.5V~28V. Suitable for work in a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 260kHz~550kHz. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Power Good, Soft Start. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . A variety of 32 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC3728". There are 32 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. dc dc voltage regulators should have a minimum input voltage of 4.5V. Statistically, DC regulator outputs 7V volts. It's important to remember that the dc dc regulator's normaloutput current is 3A, so you should note it down when starting a new project. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. DC regulator's maximum frequency is 590kHz. Communication with high quality requires 1 channels.
