IR3550MTRPBF Description

Short technical summary and product information.

The Infineon Technologies IR3550MTRPBF is an integrated PowIRstage designed as a synchronous buck gate driver. It combines a control MOSFET, synchronous MOSFET, and integrated Schottky diode for optimized performance in voltage regulation applications.

 

This component offers a high output current capability of 90A and operates with an input voltage range of 4.5V to 15V. It supports a switching frequency up to 1.0MHz, enabling efficient transient response and miniaturization of external components. Key electrical features include a PWM interface, fault protection for over temperature, shoot-through, and UVLO, and a peak efficiency of up to 95% at 1.2V.

 

The IR3550MTRPBF is housed in a compact 6mm x 6mm PQFN-32 package, suitable for surface mount applications. It is designed for efficient dual-sided cooling and operates across a temperature range of -40°C to 125°C (TJ).

 

Applications include voltage regulators for CPUs, GPUs, and DDR memory arrays, as well as high current, low profile DC-DC converters. Its design is optimized for PCB layout and heat transfer, making it suitable for demanding power delivery requirements.
