LT3840IFE#TRPBF Overview

In the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 1 numbers. PMIC packaging is solid with a Tape & Reel (TR) enclosure. The program can handle Transistor Driver dc switching's outputs (s). DC control operates at 2.5V~60V volts and has 2.5V~60V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. Switching can be done at 50kHz~1MHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a DUAL terminal on the switching converters. A variety of 28 terminations are available in dc switching. LT3840 can be used to locate other relevant dc to dc converter ics. 2.5V should be the minimum input voltage for the dc dc voltage regulator. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this.
