LTC3728LEUH-1#PBF Product Details
LTC3728LEUH-1#PBF Overview
With its 32-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For outputs of 2, this dc motor controller is suitable. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4.5V~28V and has a 4.5V~28V supply voltage. Worked in a -40°C~85°C TA dc switcher before. In this switching controller, the switch can be set to 260kHz~550kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Enable, Power Good, Soft Start. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position QUAD . The 32 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "LTC3728" will return other relevant dc to dc converter ics. 32 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4.5V. Based on the test statistics, DC regulator outputs voltage 7V. If you are starting a new project, you should note the dc dc regulator's typical output current is 3A. 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. The number of channels available for high-quality communication is 1.
