LTC3728LIUH-1#PBF Overview


As a result of 32-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. For outputs of 2, this dc motor controller is suitable. Tube is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 4.5V~35V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~85°C TA. With this switching controller, you can switch at 260kHz~550kHz. The Surface Mount makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Power Good, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at QUAD. Different dc switching's functions can be applied to 32 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics will be returned if you search "LTC3728". In total, switching converter has 32 pins. Switching converter is a type of Switching Regulator or Controllers in particular. 4.5V should be the minimum input voltage for the dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 3.35V. In most cases, the dc dc regulator's output current is 3A. This information should be noted when you begin working with the component. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. There is a maximum frequency of 590kHz on this dc regulators. Communication on 1 channels is high-quality.
