LTC3858EUH#PBF Overview
The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. For 2 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 4V~38V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller can be switched at 105kHz~835kHz 350kHz~535kHz. A generalization of dc dc regulator can be made using Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at QUAD . Various 32 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis 12V volts. Search for "LTC3858" to find other relevant dc to dc converter ics. Total pins of switching converter are 32. In particular, switching converter is a type of Switching Regulator or Controllers. 4V should be the minimum input voltage for the dc dc voltage regulator. DC regulator outputs 24V voltage based on test statistics. The dc to dc regulator is limited to 38V input voltage. It is estimated that this dc regulatorhas a maximum frequency of 850kHz. The dc to dc voltage regulator is from the PolyPhase? series. Communication with high quality requires 1 channels.
