LTC3890IGN-3#TRPBF Overview
Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. There are Transistor Driver dc switching's output (s) that it can handle. 4V~60V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a -40°C~125°C TJ rating. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . dc dc regulators can be carried out with Surface Mount. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 28 terminations with a variety of function. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 12V nominal DC switcher's voltage input. 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. Input voltage of dc dc voltage regulator should be 4V. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this.
