LTC3890IUH-2#PBF Overview


With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. 2 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. DC control operates at 4V~60V volts and has 4V~60V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. There is a switch at 105kHz~835kHz 350kHz~535kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at QUAD . A variety of 32 terminations are available in dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 12V. In addition to "LTC3890", there are other relevant dc to dc converter ics you can find. 32 pins are present on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4V. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this. There is a maximum frequency of 850kHz on this dc regulators. The dc to dc voltage regulator belongs to the PolyPhase? series.
