LTC3728LEUH-1#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. The dc motor controller is adquate to generate for 2 outputs. An enclosure of Tape & Reel (TR) is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 4.5V~28V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -40°C~85°C TA rating. It can switch at 260kHz~550kHz. The Surface Mount makes it ideal for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Power Good, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. 32 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC3728". There are a total of 32 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. A 3.35V voltage of DC regulator was detected in the test statistics. DC regulator's maximum frequency is 590kHz. Switching converter outputs current to the greatest value of 3A. Channels 1 are required for high-quality communication.
