LTC3728EUH#TRPBF Overview
Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. There is enough capacity in the dc motor controller to generate the output for the 2 input. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) can be handled by it. A 3.5V~30V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with -40°C~85°C TA. A switching controller such as this can switch at a value of 260kHz~550kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Power Good, Soft Start. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. The 32 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. LTC3728 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 32. Switching converter is a special type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 3.5V. A 5.5V voltage of DC regulator was detected in the test statistics. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. There is a maximum frequency of 590kHz on this dc regulators. To better satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES AT 5V. As a result, switching converter outputs current to the greatest value possible (3A). It is recommended that there be 1 channels for high-quality communication.
