LT3840HFE#TRPBF Overview


As a result of 28-TSSOP (0.173, 4.40mm Width) Exposed Pad compact design, the switching controller is compatible with most applications. For outputs of 1, this dc motor controller is suitable. PMIC packaging is solid with a Tape & Reel (TR) enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). 2.5V~60V is the operating voltage and supply voltage of the dc control. Suitable for work in a -40°C~150°C TJ dc switcher. With this switching controller, you can switch at 50kHz~1MHz. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position DUAL . An array of 28 terminations of dc switching. In addition to "LT3840", there are other relevant dc to dc converter ics you can find. The minimum input voltage of the dc dc voltage regulator should be 2.5V. It should be noted that the dc to dc regulator only accepts 60V voltage as input voltage.
