LTC3857IUH#TRPBF Overview
It comes in the 32-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 2 numbers. An enclosure of Tape & Reel (TR) is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. 4V~38V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with -40°C~125°C TJ. With this switching controller, you can switch at 105kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. A variety of terminations with 32 of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LTC3857". There are a total of 32 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. 4V should be the minimum input voltage for the dc dc voltage regulator. According to the test statistics, DC regulator outputs 24V voltage. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. The max frequency of the pmic can reach 850kHz. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family. Channels are 1 for high-quality communication.
