LTC3811EUHF#TRPBF Overview
With a 38-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 2 output generation. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. 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. The switching controller can be switched at 250kHz~750kHz. Surface Mount 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. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. An array of 38 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 12V. Other relevant dc to dc converter ics can be found by searching "LTC3811". 38 pins are present on switching converter. The minimum input voltage of the dc dc voltage regulator should be 4.5V. As determined by the test statistics, the output voltage of DC regulator is 3.3V. Voltages 30V are the maximum that the dc to dc regulator will accept. This dc regulatorhas a max frequency of 850kHz. Basically, it's a dc to dc voltage regulator from the PolyPhase? series. Communication with high quality requires 1 channels.
