IR3742MTRPBF Description

Short technical summary and product information.

The Infineon Technologies IR3742MTRPBF is an integrated PowIRstage synchronous buck gate driver IC. It is designed for applications requiring high efficiency at lower output voltages, such as advanced computing and data center power architectures.

 

Key electrical specifications include a 20A current output per channel, a load voltage range of 1V to 21V, and a supply voltage range of 4.5V to 7.5V. The device operates across a wide temperature range of -40°C to 125°C (TJ).

 

This IC integrates MOSFET drivers, control and synchronous MOSFETs, a Schottky diode, bootstrap diode, and an internal LDO. It supports logic-level tri-state PWM input and features over-current and over-temperature fault indications. The IR3742MTRPBF is housed in a 17-PowerVQFN package suitable for surface mounting.

 

Its design optimizes PCB layout, heat transfer, and driver/MOSFET timing, enabling high switching frequencies up to 1.5MHz for improved transient response and component miniaturization.
