The IR3859MTRPBF from Infineon Technologies is an easy-to-use, fully integrated, and highly efficient DC/DC synchronous buck regulator. Designed for space-efficient solutions, it provides accurate power delivery for low output voltage applications.
This regulator features a wide input voltage range from 1.5V to 21V and supports a continuous 9A load capability. The switching frequency is programmable from 250kHz up to 1.5MHz, allowing for optimization of the solution. It also includes essential protection functions such as pre-bias startup, hiccup current limit, and thermal shutdown for system-level security.
The IR3859MTRPBF operates within a junction temperature range of -40°C to 125°C. It is housed in a 4mm x 5mm Power QFN package, suitable for surface mount applications. The device is Halogen Free, Lead Free, and RoHS compliant.
Key applications include distributed point-of-load power architectures, server applications, netcom, computing peripheral voltage regulators, storage applications, embedded telecom systems, and general DC-DC converters.
