| Manufacturer | Richtek Technology Corporation |
| Category | Integrated Circuits (ICs) > Power Management > DC-DC Buck Converters |
| Description | 3A Synchronous Step-Down DC-DC Converter, 4.5V-28V Input, 0.76V-25V Output, -40 to 125°C, SOP-8 |
Product Overview
The RT8289GSP is a high-efficiency, synchronous rectified step-down DC-DC buck converter designed for wide input voltage industrial and consumer power systems. This device delivers up to 3A continuous output current with an input range of 4.5V to 28V and adjustable output voltage from 0.76V to 25V. It integrates low on-resistance power MOSFETs to achieve up to 95% conversion efficiency and includes internal soft-start, thermal shutdown, over-current, over-voltage, and under-voltage protection. With a fixed 500kHz switching frequency and thermally enhanced SOP-8 package, the RT8289GSP provides stable, reliable performance in high-temperature environments and space-constrained designs.
