LTC3850EUFD#TRPBF Overview

With a 28-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 2 outputs with this dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control operates at 4V~24V and has a 4V~24V supply voltage. Qualified to work in a -40°C~85°C TA dc switcher. There is a switch at 250kHz~780kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . Different dc switching's functions can be applied to 28 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Search for "LTC3850" to find other relevant dc to dc converter ics. Pins number 28 of switching converter in total. In particular, switching converter belongs to the Switching Regulator or Controllers family. 4V should be the minimum input voltage for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 23.32V voltage. DC regulator860kHz has the maximum frequency. It is recommended that there be 1 channels for high-quality communication.
