LTC3890EGN-3#TRPBF Product Details
LTC3890EGN-3#TRPBF Overview
The switching controller fits in the 28-SSOP (0.154, 3.90mm Width) package and is ideal for most applications. For outputs of 2, this dc motor controller is suitable. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. The program can handle Transistor Driver dc switching's outputs (s). 4V~60V is the supply voltage and the operating voltage of the dc control. Worked in a -40°C~125°C TJ dc switcher before. With this switching controller, you can switch at 105kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . There are many different types of terminations for 28. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. You can find other relevant dc to dc converter ics by searching "LTC3890". In particular, switching converter is a type of Switching Regulator or Controllers. 4V should be the minimum input voltage for the dc dc voltage regulator. The dc to dc regulator can only accept 60V input voltage.
