LTC3858EUFD-1#PBF Product Details
LTC3858EUFD-1#PBF Overview
Capsuled in the 28-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. PMIC is packaged in a solid enclosure of Tube. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's4V~38V is the operating voltage and supply voltage of the dc control. A -40°C~125°C TJ dc switcher is not a problem. 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. Enable, Frequency Control, Power Good, Soft Start provides dcdc regulator efficient switching control. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. An array of 28 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. There is a DC switcher's nominal voltage of 12V. You can find other relevant dc to dc converter ics by searching "LTC3858". Specially, switching converter corresponds to type Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. DC regulator outputs 5.1V voltage based on test statistics. The dc to dc regulator can only accept a maximum input voltage of 38V.
