LTC3891EUDC#TRPBF Product Details

LTC3891EUDC#TRPBF Overview


Capsuled in the 20-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. The dc motor controller is adquate to generate for 1 outputs. A solid enclosure of Tape & Reel (TR) surrounds pmic. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 4V~60V. Worked in a -40°C~125°C TJ dc switcher before. It can switch at 105kHz~835kHz 350kHz~535kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a QUAD terminal on the switching converters. The 20 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. A search for "LTC3891" will reveal other relevant dc to dc converter ics. Switching converter has a total of 20 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. 4V should be the minimum input voltage for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 24V voltage. It should be fully noted that the dc to dc regulator only accepts 60V input voltage at most. If you are starting a new project, you should note the dc dc regulator's typical output current is 5A. 835kHz is the maximum frequency of this dc regulators. As a result, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V so that the need can be met more directly.
