IR3811MTR1PBF Product Details

IR3811MTR1PBF Overview

optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. The space-saving 15-PowerVQFN package is available for this voltage regulator. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. This voltage regulator 12v reaches a switching frequency of 600kHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 2.5V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.6V. A maximum design flexibility is provided by the 7A output current of voltage regulator. There is a maximum input voltage of 21V for this voltage regulator 12v. In the particular voltage regulators, the IR3811MPBF family is represented. A voltage of 12V volts can be generated by DC DC switching regulator. There are 15 pins used for switching regulator operation. For this switching regulator, we recommend keeping the output voltage at at least 600mV volts. A 7A A maximum output current is required to meet the switching regulator operation requirements. By using the 12V's maximal output voltage, adjusting voltage regulator can operate easily. With a maximum output voltage of 12V, DC DC switching regulator has a very high efficiency. In the SupIRBuck® family, this part palys an important role in DC DC switching regulator's traget applications. This voltage regulator allows stable operation due to its high maximum operating temperature 125°C. Reliability is ensured at minimum DC DC switching regulator's operating temperatures of -40°C. With regard to the input voltage, it is compatible with a minimum voltage of 2.5V. 21V input voltage is supported at its maximum by this voltage regulator 12v.
