Description

LTC3728EUH#PBF Overview
This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. 2 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. 3.5V~30V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~85°C TA dc switcher. There is a switch at 260kHz~550kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Enable, Power Good, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . A variety of terminations with 32 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "LTC3728". There are only 32 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. DC regulator outputs 5.5V voltage according to the test statistics. normally, the dc dc regulator's output current is 25A, which you should keep in mind when starting a project. DC regulator's maximum frequency is 590kHz. The value of DC to DC voltage regulator is set to ALSO OPERATES AT 5V in order to better satisfy the requirement. Users must limit the voltage accordingly because the dc switcher's maximum input voltage is 36V. The supply voltage must be 3.5V. Output current will not exceed 5A. A high-quality communication requires 1 channels.
