LTC3858IUH#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. For outputs of 2, this dc motor controller is suitable. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). Voltages 4V~38V are the dc control's supply voltage and operating voltage, respectively. Worked in an dc switcher with a -40°C~125°C TJ rating. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Power Good, Soft Start which allows efficient switching control. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. An array of 32 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3858". There are a total of 32 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. As determined by the test statistics, the output voltage of DC regulator is 5.1V. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. 850kHz is the maximum frequency of this dc regulators. It belongs to the PolyPhase? series of dc to dc voltage regulator. Communication with high quality requires 1 channels.
