Product Overview
The IR3550MTRPBF is a 60A Integrated PowIRstage from Infineon Technologies. This highly integrated power stage combines a synchronous buck gate driver with control and synchronous MOSFETs, and a Schottky diode into a single compact package. It is designed for high-current, high-frequency DC-DC conversion applications, enabling high power density designs with minimal external components.
