LT3840MPFE Overview


The switching controller fits in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Transistor Driver dc switching's outputs (s) can be handled by it. dc control's supply and operating voltages are 2.5V~60V. Qualified to work in a -55°C~150°C dc switcher. Switching can be done at 50kHz~1MHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . The 28 terminations can be used for a wide range of dc switching. It is recommended that the dc dc voltage regulator's minimum input voltage be 2.5V. The dc to dc regulator can only accept 60V input voltage.
