LTC3890EGN-1#PBF Product Details
LTC3890EGN-1#PBF Overview
The switching controller fits in the 28-SSOP (0.154, 3.90mm Width) package and is ideal for most applications. dc motor controller is suitable for 2 output generation. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 4V~60V. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller can be switched at 105kHz~835kHz 350kHz~535kHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 28 of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 12V nominal DC switcher's voltage input. In addition to "LTC3890", there are other relevant dc to dc converter ics you can find. In total, switching converter has 28 pins. Switching converter is a type of Switching Regulator or Controllers in particular. Input voltage of dc dc voltage regulator must be 4V. Test statistics indicate DC regulator outputs 24V voltage. The dc to dc regulator can only accept 60V input voltage. You should note that the dc dc regulator's usual output current is 25A. This dc regulatorhas a max frequency of 850kHz. For high-quality communication, there are 1 channels.
