LT3840EFE#PBF Product Details

LT3840EFE#PBF Overview


Capsuled in the 28-TSSOP (0.173, 4.40mm Width) 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 1 input. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 2.5V~60V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 50kHz~1MHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the 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. You can find other relevant dc to dc converter ics by searching "LT3840". Pins number 28 of switching converter in total. Test statistics indicate DC regulator outputs 1.5V voltage. In most cases, the dc dc regulator's output current is 30A. 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 % during power-up and power-down. The maximum input voltage of dc switcher is 60V, so users should limit their voltage accordingly. Voltage 2.5V is needed for the supply. The datasheet indicates that the switching converter can output 60V volts at its maximum. 1.5V voltage output is lower than 1.5V.
