LTC3728LEUH#TRPBF Overview

In the 32-WFQFN Exposed Pad package, the switching controller meets most application requirements. dc motor controller is suitable for 2 output generation. A solid enclosure of Tape & Reel (TR) surrounds pmic. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 4.5V~28V and has a 4.5V~28V supply voltage. Work well in dc switchers with a -40°C~85°C TA. The switching controller can be switched at 260kHz~550kHz. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Enable, Power Good, Soft Start which allows efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. There are a QUAD terminal on the switching converters. A variety of terminations with 32 of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. In addition to "LTC3728", there are other relevant dc to dc converter ics you can find. 32 pins are on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. dc dc voltage regulators should have a minimum input voltage of 3.6V. Test statistics indicate DC regulator outputs 7V voltage. Considering the dc to dc regulator can only accept 30V input voltage, it is important to take note of this. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulators have a maximum frequency of 590kHz. 3A is the greatest value switching converter outputs as current. In order to ensure high-quality communication, there are 1 channels available.
