IR3899MTRPBF Description

Short technical summary and product information.

The IR3899MTRPBF from Infineon Technologies is a highly integrated and efficient synchronous buck regulator designed for various power delivery applications. This device operates within a wide input voltage range of 1V to 21V and provides an adjustable output voltage from 0.5V up to 18.06V, with a maximum output current capability of 9A.

 

Featuring a programmable switching frequency that can be set between 300kHz and 1.5MHz, the IR3899MTRPBF allows for optimization of solution size and efficiency. It includes essential protection functions such as thermally compensated current limit, over-voltage protection, and thermal shutdown for system reliability.

 

The regulator is housed in a compact 16-PowerVQFN package, measuring 4mm x 5mm, making it suitable for space-constrained designs. It is designed for surface mount applications and operates across a wide temperature range of -40°C to 125°C (TJ).

 

This component is ideal for applications requiring precise and efficient power conversion, including netcom, embedded telecom systems, server, and storage applications. Its integrated MOSFET drivers and bootstrap diode simplify external component count.
