LTC3728LEUH#PBF Product Details
LTC3728LEUH#PBF Overview
In the 32-WFQFN Exposed Pad package, the switching controller meets most application requirements. For 2 outputs, the dc motor controller is appropriate. Packaging for the pmic consists of Tube solid enclosures. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 4.5V~28V and has a 4.5V~28V supply voltage. Suitable for work in a -40°C~85°C TA dc switcher. The switching controller can be switched at 260kHz~550kHz. A generalization of dc dc regulator can be made using Surface Mount. To provide efficient switching control, Enable, Power Good, Soft Start is included in the dcdc regulator. An analog IC with the DUAL SWITCHING CONTROLLER signal 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. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Search for "LTC3728" to find other relevant dc to dc converter ics. There are 32 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5.5V voltage. You should note down the dc dc regulator's usual output current of 3A when you start a project. DC switcher's Surface Mount qualifies it for most applications and prototypes. DC regulator's maximum frequency is 590kHz. The maximum input voltage of the dc switcher is 28V, so users need to limit the voltage accordingly. Switching controller is necessary to have a supply voltage of 4.5V. Channels are 1 for high-quality communication.
