LTC3858EGN-1#PBF Product Details

LTC3858EGN-1#PBF Overview


With its 28-SSOP (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For outputs of 2, this dc motor controller is suitable. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4V~38V and has a 4V~38V supply voltage. Worked in a -40°C~125°C TJ dc switcher before. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 28 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Searching "LTC3858" will return other relevant dc to dc converter ics. 28 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4V. Based on the test statistics, DC regulator outputs voltage 24V. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. There is a maximum frequency of 850kHz on this dc regulators. The number of channels available for high-quality communication is 1.
