Description
LTC3890EUH#PBF Overview
With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 4V~60V. Worked in an dc switcher with a -40°C~125°C TJ rating. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. An array of 32 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. Search for "LTC3890" to find other relevant dc to dc converter ics. There are a total of 32 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4V. The test statistics indicate that DC regulator outputs a voltage of 24V. At most, the dc to dc regulator accepts 60V input voltage. You should note that the dc dc regulator's usual output current is 25A. DC regulator has a maximum frequency of 850kHz. The dc to dc voltage regulator belongs to the PolyPhase® series. There are 1 channels for high-quality communication.
