LTC3890IUH-2#TRPBF Overview
It comes in a 32-WFQFN Exposed Pad package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 2. There is a Tape & Reel (TR) solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control operates at 4V~60V and has a 4V~60V supply voltage. Suitable for work in a -40°C~125°C TJ dc switcher. There is a switch at 105kHz~835kHz 350kHz~535kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking which allows efficient switching control. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . An array of 32 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. Other relevant dc to dc converter ics can be found by searching "LTC3890". Particularly, switching converter is a type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4V. Voltages 60V are the maximum that the dc to dc regulator will accept. There are several dc to dc voltage regulator in the PolyPhase? series.
