LT3840HFE#TRPBF Product Details
LT3840HFE#TRPBF 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 Tape & Reel (TR) 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~150°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". An input voltage of 2.5V is the minimum required for the dc dc voltage regulator. A maximum voltage of 60V is accepted by the dc to dc regulator as an input voltage.
