LTC3728LZEUH#TRPBF Overview
The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. This dc motor controller can be used to generate outputs with 2 numbers. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. Transistor Driver dc switching's outputs (s) are supported. Voltages 4.5V~28V are the dc control's supply voltage and operating voltage, respectively. Worked in a -40°C~85°C TA dc switcher before. The switching controller can be switched at 260kHz~550kHz. dc dc regulator can be generalized using Surface Mount. To provide efficient switching control, Enable, Power Good, Soft Start is included in the dcdc regulator. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the QUAD position. The 28 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. LTC3728 can be searched for other relevant dc to dc converter ics. 32 pins are on switching converter. Input voltage of dc dc voltage regulator should be 4.5V. There is a maximum frequency of 590kHz for this dc regulators. Switching converter outputs current to the greatest value of 3A. Channels 1 are required for high-quality communication.
