LTC3861EUH-1#TRPBF Overview
The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Tape & Reel (TR) solid enclosure protects the pmic. A total of PWM Signal dc switching's outputs can be handled by it. DC control operates at 3V~5.5V volts and has 3V~5.5V supply voltage. Suitable for work in a -40°C~125°C TJ dc switcher. Switching can be done at 250kHz~3MHz with this switching controller. Surface Mount makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. Various 32 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 5V. Searching "LTC3861" will return other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. An input voltage of 3V is the minimum required for the dc dc voltage regulator. Considering the dc to dc regulator can only accept 5.5V input voltage, it is important to take note of this. The dc to dc voltage regulator belongs to the PolyPhase? series.
