LTC3891HFE#PBF Overview


It comes in the 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package, which makes switching controller suitable for most applications. 1 outputs can be generated with the dc motor controller. There is a Tube solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4V~60V is the supply voltage and the operating voltage of the dc control. Qualified to work in a -40°C~150°C TJ dc switcher. It can switch at 105kHz~835kHz 350kHz~535kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at DUAL. 20 terminations with a variety of function. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. You can find other relevant dc to dc converter ics by searching "LTC3891". Pins number 20 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4V. The test statistics indicate that DC regulator outputs a voltage of 24V. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this. You should note down the dc dc regulator's usual output current of 5A when you start a project. It is estimated that this dc regulatorhas a maximum frequency of 835kHz. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V.
