LTC3858IUFD-1#TRPBF Overview
In the 28-WFQFN Exposed Pad package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 4V~38V voltage are supplied and operated. Worked in a -40°C~125°C TJ dc switcher before. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start provides dcdc regulator efficient switching control. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . There are many different types of terminations for 28. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 12V nominal DC switcher's voltage input. Search for "LTC3858" to find other relevant dc to dc converter ics. There are a total of 28 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4V. Based on the test statistics, DC regulator outputs voltage 24V. A maximum voltage of 38V is accepted by the dc to dc regulator as an input voltage. 850kHz is the maximum frequency of this dc regulators. Channels are 1 for high-quality communication.
