LTC3869IUFD#TRPBF Product Details
LTC3869IUFD#TRPBF Overview
Capsuled in the 28-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. 2 outputs are supported by the dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. Transistor Driver dc switching's outputs (s) are supported. 4V~38V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~125°C TJ. It can switch at 250kHz~780kHz. The Surface Mount value makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. QUAD are the position of the terminal of the switching converters. 28 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 15V volts. LTC3869 can be searched for other relevant dc to dc converter ics. There are a total of 28 pins on switching converter. This dc dc voltage regulator should be powered by a voltage of 4V. Statistically, the DC regulator outputs 12.5V voltage. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. A starting point for a project is to note down the dc dc regulator's usual output current, which is 25A. There is a maximum frequency of 850kHz on this dc regulators. Channels 1 are required for high-quality communication.
