LTC3890MPUH-2#PBF Overview
As a result of 32-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. It is sufficient to generate 2 outputs with this dc motor controller. The pmic is packaged in Tube solid enclosure. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 4V~60V and has a 4V~60V supply voltage. Worked in a -55°C~150°C TJ dc switcher before. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . A variety of 32 terminations are available in dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. LTC3890 can be searched for other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4V. The dc to dc regulator is limited to 60V input voltage. Thare are switch converters of the PolyPhase? series.
