LTC3857EUH#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. For 2 outputs, the dc motor controller is appropriate. An enclosure of Tape & Reel (TR) is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. DC control operates at 4V~38V volts and has 4V~38V supply voltage. Suitable for working in an dc switcher that has a -40°C~125°C TJ. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at QUAD . There are many different types of terminations for 32. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3857". Switching converter has a total of 32 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4V. Test statistics indicate DC regulator outputs 24V voltage. The dc to dc regulator can only accept 38V input voltage. There is a maximum frequency of 850kHz on this dc regulators. The dc to dc voltage regulator belongs to the PolyPhase? series. In order to ensure high-quality communication, there are 1 channels available.
