LT3840IUFE#PBF Overview
As a result of 38-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. DC control operates at 2.5V~60V volts and has 2.5V~60V supply voltage. Worked in an dc switcher with a -40°C~125°C TJ rating. The switching controller can be switched at 50kHz~1MHz. The Surface Mount makes it ideal for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. Different dc switching's functions can be applied to 38 terminations. 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. This dc to dc regulator accepts only 60V input voltage at most.
