LT3840IUFE#TRPBF Overview


In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 2.5V~60V and has a 2.5V~60V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. It can switch at 50kHz~1MHz. 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. SWITCHING CONTROLLER analog IC connects the switch converters. QUAD are the position of the terminal of the switching converters. Different dc switching's functions can be applied to 38 terminations. Other relevant dc to dc converter ics can be found by searching "LT3840". An input voltage of 2.5V is the minimum required for the dc dc voltage regulator. Voltages 60V are the maximum that the dc to dc regulator will accept.
