LTC3728EG#TRPBF Overview
Capsuled in the 28-SSOP (0.209, 5.30mm Width) package, the switching controller suits most application needs. It is sufficient to generate 2 outputs with this dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 3.5V~30V. Worked in an dc switcher with a -40°C~85°C TA rating. It can switch at 260kHz~550kHz. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Enable, Power Good, Soft Start is included in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. A variety of dc switching's functions can be performed on 28 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "LTC3728" will return other relevant dc to dc converter ics. 28 pins are on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 3.5V. DC regulator outputs 5.5V voltage according to the test statistics. At most, the dc to dc regulator accepts 36V input voltage. There is a maximum frequency of 590kHz on this dc regulators. As a result, DC to DC voltage regulator has a value of ALSO OPERATES AT 5V so that the need can be met more directly. Whenever the current value is 3A, switching converter outputs the highest possible value. Channels 1 are required for high-quality communication.
