LTC3728LIGN-1#PBF Overview


This switching controller fits most application requirements since it is packaged in a 28-SSOP (0.154, 3.90mm Width) package. dc motor controller is suitable for 2 output generation. PMIC is packaged in a solid enclosure of Tube. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc controls with 4.5V~35V voltage are supplied and operated. Work well in dc switchers with a -40°C~85°C TA. Switching can be done at 260kHz~550kHz with this switching controller. dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by Enable, Power Good, Soft Start. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. 28 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. In addition to "LTC3728", there are other relevant dc to dc converter ics you can find. Pins number 28 of switching converter in total. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. DC regulator outputs 3.35V voltage according to the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 3A, so you should note it down when starting a new project. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThe max frequency of the pmic can reach 590kHz. It is recommended that there be 1 channels for high-quality communication.
