DUAL SWITCHING CONTROLLER |
LTC3811EUHF#PBF Overview
It comes in the 38-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. 2 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tube. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 4.5V~30V and has a 4.5V~30V supply voltage. Qualified to work in a -40°C~85°C TA dc switcher. Switching can be done at 250kHz~750kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. Current Limit, Enable, Phase Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position QUAD . Different dc switching's functions can be applied to 38 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. LTC3811 can be searched for other relevant dc to dc converter ics. Pins number 38 of switching converter in total. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. A 3.3V voltage of DC regulator was detected in the test statistics. At most, the dc to dc regulator accepts 30V input voltage. The max frequency of the pmic can reach 850kHz. It belongs to the dc to dc voltage regulator series PolyPhase?. For high-quality communication, there are 1 channels.
