LTC3858IUH#PBF Overview


With its 32-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For 2 outputs, the dc motor controller is appropriate. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4V~38V. Worked in a -40°C~125°C TJ dc switcher before. 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. Current Limit, Enable, Frequency Control, Power Good, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at QUAD. A variety of terminations with 32 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. In addition to "LTC3858", there are other relevant dc to dc converter ics you can find. 32 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. An input voltage of 4V is the minimum required for the dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 24V. Voltages 38V are the maximum that the dc to dc regulator will accept. This dc regulatorhas a max frequency of 850kHz. It belongs to the PolyPhase? series of dc to dc voltage regulator. A high-quality communication requires 1 channels.
