Infineon Technologies AG Voltage Regulators - DC DC Switching Regulators IR3811MTR1PBF

The IR3811MTR1PBF is a highly integrated synchronous buck regulator capable of delivering a continuous load of up to 7A. It operates over a wide input voltage range of 2.5V to 21V and can provide an adjustable output voltage from 0.6V to 12V. The device features a fixed switching frequency of 600kHz, which allows for the use of smaller external components, enhancing its space efficiency. Key features include programmable over-current protection, hiccup current limit, and thermal protection, ensuring reliable operation under fault conditions. The IR3811 also supports pre-bias startup and programmable soft-start, making it suitable for various applications, including distributed point-of-loads, server and workstation power supplies, and memory applications. The compact 5mm x 6mm QFN package design further contributes to its suitability for space-constrained environments. The product is RoHS compliant, ensuring it meets environmental standards.
