LTC3728LIGN#TRPBF Product Details
LTC3728LIGN#TRPBF Overview
Capsuled in the 28-SSOP (0.154, 3.90mm 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 Tape & Reel (TR) 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 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. An input voltage of 3.6V is the minimum required for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 3.35V voltage. A maximum voltage of 30V is accepted by the dc to dc regulator as an input voltage. It is estimated that this dc regulatorhas a maximum frequency of 590kHz. A maximum value of 3A is output for current. Channels are 1 for high-quality communication.
