LTC3858IUH-2#PBF Overview


With its 32-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. 2 outputs can be generated with the dc motor controller. There is a Tube solid enclosure around 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. Suitable for work in a -40°C~125°C TJ dc switcher. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start is used for efficient switching control in the dcdc regulator. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at QUAD. There are many different types of terminations for 32. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. In addition to "LTC3858", there are other relevant dc to dc converter ics you can find. 32 pins are on switching converter. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. Test statistics indicate DC regulator outputs 5.1V voltage. Voltages 38V are the maximum that the dc to dc regulator will accept. DC regulator850kHz has the maximum frequency. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family. Communication with high quality requires 1 channels.
