Description
LT3840IUFE#PBF Overview
Capsuled in the 38-WFQFN Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 2.5V~60V. Qualified to work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 50kHz~1MHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the QUAD position. 38 terminations with a variety of function. Other relevant dc to dc converter ics can be found by searching "LT3840". The minimum input voltage of the dc dc voltage regulator should be 2.5V. It should be fully noted that the dc to dc regulator only accepts 60V input voltage at most.
