LT3840IFE Overview
It comes in a 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. 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. Qualified to work in a -40°C~125°C dc switcher. It can switch at 50kHz~1MHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. DUAL are the position of the terminal of the switching converters. A variety of dc switching's functions can be performed on 28 terminations. dc dc voltage regulators should have a minimum input voltage of 2.5V. It should be noted that the dc to dc regulator only accepts 60V voltage as input voltage.
