LTC3891MPFE#TRPBF Overview


It comes in a 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With Transistor Driver dc switching's output (s), it is able to handle it. 4V~60V is the supply voltage and the operating voltage of the dc control. Suitable for a -55°C~150°C TJ dc switcher. It can switch at 105kHz~835kHz 350kHz~535kHz. The Surface Mount value makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a DUAL terminal on the switching converters. A variety of dc switching's functions can be performed on 20 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. You can find other relevant dc to dc converter ics by searching "LTC3891". There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. DC regulator outputs 5.1V voltage based on test statistics. The dc to dc regulator can only accept a maximum input voltage of 60V. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V.
