RichTek Technology Corporation Integrated Circuits (ICs) - Power Management (PMIC) - Voltage Regulators - DC DC Switching Regulators RT8098DHGE

The RT8098D is a synchronous step-down DC-DC converter designed for efficient power management in various applications. It operates within an input voltage range of 2.7V to 6V and can deliver an output current of up to 2.5A. The output voltage can be adjusted between 0.6V and 3.4V, making it suitable for a range of voltage requirements. This device utilizes Current Mode Constant On-Time (CMCOT) control architecture, which allows for a fast transient response and maintains a nearly constant switching frequency of 1MHz. The integrated low RDS(ON) power MOSFETs contribute to high efficiency, reaching up to 95%. The RT8098D includes several protection features such as over-current protection, input under-voltage lockout, output under-voltage protection, and thermal shutdown, ensuring reliable operation under various conditions. The product is packaged in a compact SOT-23-6 form factor, making it suitable for surface mount applications. It is particularly well-suited for use in set-top boxes, cable modems, xDSL platforms, and LCD TV power supplies.
