INFINEON IR3883MTRPBF Synchronous Buck Regulator

The IR3883 is a highly efficient, fully integrated synchronous buck regulator designed for accurate power delivery in power management applications. It operates over a wide input voltage range from 2.5V to 14V, delivering up to 3A load current at 800kHz switching frequency. Its enhanced stability engine allows ceramic capacitor operation without external compensation. Features include soft-start, thermal shutdown, over-current, over-voltage protections, and a power good output. Compact 3x3 mm PQFN package makes it suitable for server, storage, communication infrastructure, and point of load architectures, providing reliable and efficient voltage regulation.
