LT3840HFE Overview


With its 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control operates at 2.5V~60V and has a 2.5V~60V supply voltage. Workable in an dc switcher where -40°C~150°C is the -40°C~150°Crm. Using this switching controller, it is possible to 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. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . There are many different types of terminations for 28. It is recommended to use 2.5V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator can only accept a maximum input voltage of 60V.
