LT3840HFE#PBF Product Details

LT3840HFE#PBF 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. Packaging for the pmic consists of Tube solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 2.5V~60V voltage are supplied and operated. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. There is a switch at 50kHz~1MHz that can be used with this controller. The Surface Mount allows it to be used for dc dc regulator in general. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a DUAL terminal on the switching converters. 28 terminations with a variety of function. LT3840 can be searched for other relevant dc to dc converter ics. There are 28 pins on switching converter. Statistically, the DC regulator outputs 1.5V voltage. You should note down the dc dc regulator's usual output current of 30A when you start a project. The maximum duty cycle of this voltage regulator dc to dc is set to 99 % to ensure reliability during power-up and power-down. Since the dc switcher's maximum input voltage is 60V, the voltage must be regulated accordingly. Voltage 2.5V is needed for the supply. Datasheets state the switching converter can output up to 60V volts. voltage controllers with a minimum voltage output of 1.5V cannot operate.
