## Description

The IR3898MTRPBF from Infineon Technologies is a highly integrated and efficient DC-DC buck regulator. Designed for ease of use, it incorporates PWM controller and MOSFETs in a compact 4mm x 5mm PQFN package, making it a space-efficient solution for accurate power delivery.

This versatile regulator operates with a wide input voltage range from 1.0V to 21V (with external Vcc) and offers an output voltage range of 0.5V to 0.86x Vin. The switching frequency is programmable from 300kHz to 1.5MHz, allowing for optimization of the solution. It supports a continuous output current of up to 6A.

Key features include enhanced line/load regulation with feed-forward, internal digital soft-start/soft-stop, and thermally compensated current limit with hiccup mode overcurrent protection. It also includes an internal LDO to improve light load and full load efficiency, external synchronization capability, and enhanced pre-bias start-up. The operating temperature range is -40°C to 125°C.

The IR3898MTRPBF is suitable for applications such as Netcom, embedded telecom systems, server applications, storage applications, and distributed point-of-load power architectures. It is lead-free, halogen-free, and RoHS compliant.
