LT3840EFE Overview
It comes in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, which makes switching controller suitable for most applications. 1 outputs can be generated with the dc motor controller. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 2.5V~60V volts and has 2.5V~60V supply voltage. A -40°C~125°C dc switcher is not a problem. The switching controller can be switched at 50kHz~1MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of dc switching's functions can be performed on 28 terminations. It is recommended that the dc dc voltage regulator's minimum input voltage be 2.5V. It should be noted that the dc to dc regulator only accepts 60V voltage as input voltage.
