LTC3728IUH#PBF Overview


With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. This dc motor controller can be used to generate outputs with 2 numbers. A solid enclosure of Tube surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 3.5V~30V. Suitable for working in an dc switcher that has a -40°C~85°C TA. The switching controller is capable of switching at the 260kHz~550kHz position. dc dc regulator can be generalized using Surface Mount. For efficient switching control, the dcdc regulator features Enable, Power Good, Soft Start. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. Different dc switching's functions can be applied to 32 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. LTC3728 can be searched for other relevant dc to dc converter ics. 32 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 5.5V voltage. In most cases, the dc dc regulator's output current is 25A. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 99.4 % during power-up and power-down. It is estimated that this dc regulatorhas a maximum frequency of 590kHz. This value is ALSO OPERATES AT 5V so that DC to DC voltage regulator better serves the purpose. In order to ensure the dc switcher's functionality, users must limit the voltage to 36V due to the dc switcher's maximum input voltage. Switching controller is necessary to have a supply voltage of 3.5V. Communication on 1 channels is high-quality.
