LT3840EFE#TRPBF Product Details
LT3840EFE#TRPBF Overview
It comes in a 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, so switching controller can be used for most applications. dc motor controller is suitable for 1 output generation. There is a Tape & Reel (TR) solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 2.5V~60V. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. Switching can be done at 50kHz~1MHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. A variety of terminations with 28 of dc switching. LT3840 can be used to locate other relevant dc to dc converter ics. Input voltage of dc dc voltage regulator must be 2.5V. The dc to dc regulator can only accept 60V input voltage.
