LTC3728LIGN#TRPBF Overview
Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For outputs of 2, this dc motor controller is suitable. A solid enclosure of Tape & Reel (TR) surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 4.5V~28V voltage are supplied and operated. Work well in dc switchers with a -40°C~85°C TA. The switching controller can be switched at 260kHz~550kHz. The Surface Mount value makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Power Good, Soft Start. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. The 28 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. You can find other relevant dc to dc converter ics by searching "LTC3728". In total, switching converter has 28 pins. Switching converter is a type of Switching Regulator or Controllers in particular. 3.6V should be the minimum input voltage for the dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 3.35V. The dc to dc regulator can only accept a maximum input voltage of 30V. The max frequency of the pmic can reach 590kHz. Switching converter outputs current to the greatest value of 3A. There are 1 channels for high-quality communication.
