LTC3890HGN-3#PBF Overview


With its 28-SSOP (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. It is sufficient to generate 2 outputs with this dc motor controller. Tube solid enclosure protects the pmic. There are Transistor Driver dc switching's output (s) that it can handle. A 4V~60V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~150°C TJ rating. There is a switch at 105kHz~835kHz 350kHz~535kHz that can be used with this controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . A variety of 28 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. You can find other relevant dc to dc converter ics by searching "LTC3890". There are only 28 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. This dc to dc regulator accepts only 60V input voltage at most. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 99 %.
