LTC3728LXCUH#PBF Product Details
LTC3728LXCUH#PBF Overview
It comes in the 32-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. dc motor controller is suitable for 2 output generation. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. 4.5V~28V is the operating voltage and supply voltage of the dc control. Suitable for work in a 0°C~85°C TA dc switcher. The switching controller is capable of switching at the 260kHz~550kHz position. A generalization of dc dc regulator can be made using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Power Good, Soft Start. Search for "LTC3728" to find other relevant dc to dc converter ics. Pins number 32 of switching converter in total. Test statistics indicate DC regulator outputs 7V voltage. You should note down the dc dc regulator's usual output current of 25A when you start a project. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. There is a maximum frequency of 590kHz for this dc regulators. The temperature should be at least 0°C. DC regulator should run at a temperature of 85°C more than 85°C degrees Celsius. The dc switcher's maximum input voltage is 28V, so users must limit the voltage accordingly. A 32-QFN (5x5) would be the supplier dc dc controller package for this part. The supply voltage must be 4.5V. There are 1 channels for high-quality communication.
