LTC3891MPFE#PBF Overview

This switching controller fits most application requirements since it is packaged in a 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package. Packaging for the pmic consists of Tube solid enclosures. 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. Workable in an dc switcher where -55°C~150°C TJ is the -55°C~150°C TJrm. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . A generalization of dc dc regulator can be made using Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 20 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. Other relevant dc to dc converter ics can be found by searching "LTC3891". The switching converter has a total of 20 pins. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, DC regulator outputs 24V volts. If you start a project, note down the dc dc regulator's usual output current of 5A. A duty cycle set at 99 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controller operates at 900kHz Hz. The value of DC to DC voltage regulator is set to ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V in order to better satisfy the requirement. You can set the input voltage to 12V for nominal working status. The controller switches with phase number 1.
