LTC3870IUFD#TRPBF Product Details
LTC3870IUFD#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 28-WFQFN Exposed Pad package. There is enough capacity in the dc motor controller to generate the output for the 2 input. There is a Tape & Reel (TR) solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). 4.5V~60V is the supply voltage and the operating voltage of the dc control. Qualified to work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable, Frequency Control, Phase Control, Soft Start provides dcdc regulator efficient switching control. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. An array of 28 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. A search for "LTC3870" will reveal other relevant dc to dc converter ics. There is a particular type of Switching Regulator or Controllers in switching converter. dc dc voltage regulators should have a minimum input voltage of 4.5V. According to the test statistics, DC regulator outputs 5.1V voltage. Voltages 60V are the maximum that the dc to dc regulator will accept. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.5V TO 14V. 0.1A is the greatest value switching converter outputs as current. It belongs to the dc to dc voltage regulator series PolyPhase?.
