LT3840IFE#PBF Overview


It comes in a 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, so switching controller can be used for most applications. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. 2.5V~60V is the supply voltage and the operating voltage of the dc control. Suitable for work in a -40°C~125°C TJ dc switcher. In this switching controller, the switch can be set to 50kHz~1MHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a DUAL terminal on the switching converters. Various 28 terminations. You can find other relevant dc to dc converter ics by searching "LT3840". This dc dc voltage regulator should be powered by a voltage of 2.5V. A maximum voltage of 60V is accepted by the dc to dc regulator as an input voltage.
