LTC3890HUH-2#TRPBF Overview
With its 32-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For 2 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). 4V~60V is the operating voltage and supply voltage of the dc control. A -40°C~150°C TJ dc switcher is not a problem. This switching controller can switch at 105kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . A variety of dc switching's functions can be performed on 32 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The nominal DC switcher's voltage input is 12V. A search for "LTC3890" will reveal other relevant dc to dc converter ics. There is a particular type of Switching Regulator or Controllers in switching converter. The minimum input voltage of the dc dc voltage regulator should be 4V. It should be noted that the dc to dc regulator only accepts 60V voltage as input voltage. Thare are switch converters of the PolyPhase? series.
