LTC3858IUH-2#TRPBF Product Details
LTC3858IUH-2#TRPBF Overview
Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. A solid enclosure of Tape & Reel (TR) surrounds pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 4V~38V. Suitable for a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 105kHz~835kHz 350kHz~535kHz. The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start for efficient switching control. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a terminal (s) on the switching converters that are designed at QUAD. A variety of 32 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. You can find other relevant dc to dc converter ics by searching "LTC3858". Total pins of switching converter are 32. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. Statistically, DC regulator outputs 24V volts. A maximum voltage of 38V is accepted by the dc to dc regulator as an input voltage. There is a maximum frequency of 850kHz for this dc regulators. There are several dc to dc voltage regulator in the PolyPhase? series. Channels 1 are required for high-quality communication.
