LTC3728EG#PBF Product Details
LTC3728EG#PBF Overview
Capsuled in the 28-SSOP (0.209, 5.30mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 3.5V~30V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~85°C TA. Using this switching controller, it is possible to switch at 260kHz~550kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Power Good, Soft Start. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 28 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "LTC3728". Pins number 28 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 36V voltage. In most cases, the dc dc regulator's output current is 3A. This information should be noted when you begin working with the component. Switching controller operates at 550kHz Hz. The value of DC to DC voltage regulator is set at ALSO OPERATES AT 5V in order to fulfill the requirements more effectively. It is possible to set the input voltage as 15V for nominal working statuses. The maximum input voltage of dc switcher is 36V, so users should limit their voltage accordingly. Voltage 3.5V is needed for the supply. 800mV voltage output is lower than 800mV. Channels are 1 for high-quality communication. If there is 450μA current flow input, then the switching converter could operate.
