LTC3728LIUH#PBF Product Details

LTC3728LIUH#PBF Overview


With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 4.5V~28V. Worked in an dc switcher with a -40°C~85°C TA rating. Switching can be done at 260kHz~550kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Power Good, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. 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. The nominal DC switcher's voltage input is 15V. Search for "LTC3728" to find other relevant dc to dc converter ics. There are a total of 32 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 3.6V. The test statistics indicate that DC regulator outputs a voltage of 7V. At most, the dc to dc regulator accepts 30V input voltage. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulator has a maximum frequency of 590kHz. Current is output to the greatest value of 3A. There are 1 channels for high-quality communication.
