LTC3891EFE#TRPBF Product Details

LTC3891EFE#TRPBF Overview


Capsuled in the 20-TSSOP (0.173, 4.40mm Width) 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. PMIC is packaged in a solid enclosure of Tape & Reel (TR). The system can process Transistor Driver dc switching's outputs (s). A 4V~60V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~125°C TJ rating. The switching controller can be switched at 105kHz~835kHz 350kHz~535kHz. dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . There are many different types of terminations for 20. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3891". In total, switching converter has 20 pins. The type is a particular Switching Regulator or Controllers of switching converter. It is recommended that the input voltage of the dc dc voltage regulator be 4V. DC regulator outputs 24V voltage according to the test statistics. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this. If you are starting a new project, you should note the dc dc regulator's typical output current is 5A. DC regulator's maximum frequency is 835kHz. 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.
