LTC3858EUH-2#TRPBF Overview


Capsuled in the 32-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. This dc motor controller can be used to generate outputs with 2 numbers. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4V~38V and has a 4V~38V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. A switching converters's terminal (s) sits at the QUAD position. 32 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. You can find other relevant dc to dc converter ics by searching "LTC3858". There are a total of 32 pins on switching converter. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 5.1V. The dc to dc regulator can only accept a maximum input voltage of 38V. 850kHz is the maximum frequency of this dc regulators. The dc to dc voltage regulator belongs to the PolyPhase? series. Channels 1 are required for high-quality communication.
