Description
LTC3728LEUH#PBF Overview
Capsuled in the 32-WFQFN Exposed Pad 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 4.5V~28V 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 QUAD position. A variety of dc switching's functions can be performed on 32 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 32 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 5.5V 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. The Surface Mount makes DC switcher suitable for most applications and prototypes. It is estimated that this dc regulatorhas a maximum frequency of 590kHz. The maximum input voltage of dc switcher is 28V, so users should limit their voltage accordingly. Voltage 4.5V is needed for the supply. Channels are 1 for high-quality communication.
