LTC3870EUFD#TRPBF Product Details
LTC3870EUFD#TRPBF Overview
It comes in a 28-WFQFN Exposed Pad package, so switching controller can be used for most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. The pmic is packaged in Tape & Reel (TR) solid enclosure. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 4.5V~60V volts and has 4.5V~60V supply voltage. Worked in an dc switcher with a -40°C~125°C TJ rating. A switching controller such as this can switch at a value of 500kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. Current Limit, Enable, Frequency Control, Phase Control provides dcdc regulator efficient switching control. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. An array of 28 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. In addition to "LTC3870", there are other relevant dc to dc converter ics you can find. In particular, switching converter belongs to the Switching Regulator or Controllers family. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 5.1V. Voltages 60V are the maximum that the dc to dc regulator will accept. DC to DC voltage regulator has the value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.5V TO 14V to better satisfy the requirement. 0.1A is the greatest value switching converter outputs as current. It belongs to the PolyPhase? series of dc to dc voltage regulator.
