Infineon Technologies' SupIRBuck® series IR3891MTRPBF is a highly efficient, dual-output, synchronous buck switching regulator. This adjustable positive voltage regulator is designed for demanding applications, offering up to 4A of output current per channel from a single IC. The output voltage is adjustable from 0.5V up to 18.06V, with a wide input voltage range of 1V to 21V. Featuring a flexible switching frequency range of 300kHz to 1.5MHz, the IR3891MTRPBF allows for optimization of component size and efficiency. Its integrated synchronous rectifier eliminates the need for a Schottky diode, further enhancing performance and reducing component count. The 31-PowerVFQFN package with a 5x6 PQFN footprint is suitable for surface mount applications. This component is commonly utilized in industrial automation, telecommunications infrastructure, and computing power management systems.
