LTC3858EGN-1#TRPBF Product Details
LTC3858EGN-1#TRPBF Overview
It comes in a 28-SSOP (0.154, 3.90mm Width) package, so switching controller can be used for most applications. 2 outputs are supported by the dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. Transistor Driver dc switching's outputs (s) can be handled by it. A 4V~38V voltage is supplied to the dc control and used for operating it. Work well in dc switchers with a -40°C~125°C TJ. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. A variety of 28 terminations are available in dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3858". There are only 28 pins on switching converter. Switching converter is a special 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. A maximum voltage of 38V is accepted by the dc to dc regulator as an input voltage. This dc regulatorhas a max frequency of 850kHz. A high-quality communication requires 1 channels.
