LTC3728EUH#PBF Overview
The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. 2 outputs can be generated with the dc motor controller. A solid enclosure of Tube surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). 3.5V~30V is the operating voltage and supply voltage of the dc control. A -40°C~85°C TA dc switcher is not a problem. 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. Enable, Power Good, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. The switching converters's terminals (s) are designed at QUAD. An array of 32 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including 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. The switching converter has a total of 32 pins. Switching converter is a special type of Switching Regulator or Controllers. DC regulator outputs 5.5V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 25A. DC regulator590kHz has the maximum frequency. DC to DC voltage regulator has the value of ALSO OPERATES AT 5V to better satisfy the requirement. Users must limit the voltage accordingly because the dc switcher's maximum input voltage is 36V. Switching controller is necessary to have a supply voltage of 3.5V. Input current cannot exceed 5A with this dc switcher. Communication on 1 channels is high-quality.
