LTC3858EUH-2#PBF Product Details
LTC3858EUH-2#PBF Overview
In the 32-WFQFN Exposed Pad package, the switching controller meets most application requirements. 2 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. 4V~38V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~125°C TJ. There is a switch at 105kHz~835kHz 350kHz~535kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start which allows efficient switching control. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at QUAD. 32 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. It is inputted with a DC switcher's voltage of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3858". Switching converter has a total of 32 pins. The minimum input voltage of the dc dc voltage regulator should be 4V. Test statistics indicate DC regulator outputs 24V voltage. Voltages 38V are the maximum that the dc to dc regulator will accept. DC regulator850kHz has the maximum frequency. It belongs to the PolyPhase? series of dc to dc voltage regulator. Communication with high quality requires 1 channels.
