IR3551MTRPBF Description

Short technical summary and product information.

The Infineon Technologies IR3551MTRPBF is an integrated PowIRstage designed for high-current voltage regulation applications such as CPUs, GPUs, and DDR memory arrays. This device combines a gate driver, control MOSFET, synchronous MOSFET, and Schottky diode into a single package.

 

Key electrical specifications include an input voltage operating range of 4.5V to 15V and an output current capability of 50A DC. It supports a switching frequency up to 1.0MHz, enabling high performance transient response and allowing for miniaturization of external components. The device achieves peak efficiency up to 94.5% at 1.2V and features a diode-emulation high-efficiency mode for improved light-load performance.

 

Additional features include an integrated current sense amplifier for accurate current monitoring, VCC under-voltage lockout, and a thermal flag for protection. The IR3551MTRPBF is compatible with 3.3V PWM logic and is VCC tolerant. It also supports Body-Braking® load transient response.

 

The component is housed in a small 5mm x 6mm x 0.9mm PQFN package, suitable for surface mounting. It is designed for efficient dual-sided cooling and is lead-free and RoHS compliant. The PCB footprint is compatible with IR3550 and IR3553 devices.
