LTC3858IUFD-1#PBF Overview


In the 28-WFQFN Exposed Pad package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 4V~38V. Work well in dc switchers with a -40°C~125°C TJ. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start which allows efficient switching control. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. switching converters terminal (s) are designed to be at QUAD. There are many different types of terminations for 28. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. LTC3858 can be searched for other relevant dc to dc converter ics. The switching converter has a total of 28 pins. Switching converter type is specifically Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 24V. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. There is a maximum frequency of 850kHz for this dc regulators. Communication with high quality requires 1 channels.
