Overview
The DA9130-XXRT2 is a dual-phase, high-efficiency DC-DC converter from the Renesas DA9130 series. It integrates two independent synchronous buck converters capable of delivering up to 10A per channel. The device features an I2C-compatible interface for dynamic voltage scaling and configuration. It operates with an input voltage range of 2.5V to 5.5V and supports output voltages from 0.3V to 1.9V. Key specifications include a nominal switching frequency of 4MHz, ±1% static accuracy, and integrated soft-start functionality.
Feature Summary
- Dual-channel architecture providing independent power rails with integrated synchronous FETs
- I2C-compatible interface enabling programmable control and dynamic voltage adjustment
- Integrated protection mechanisms including over-current, over-temperature, and undervoltage lockout
Applications
- High-performance processing systems requiring efficient multi-rail power delivery
- Automotive infotainment and telematics units
- Advanced Driver Assistance Systems (ADAS) controllers
Procurement Notes
Verify the specific suffix in the part number against official documentation to confirm exact electrical characteristics and package options. Confirm availability status as supply conditions may vary by region. Ensure compatibility with existing PCB footprint and thermal design requirements before integration.
Selection Notes
Select this component for applications demanding high current density and compact form factors. Evaluate thermal performance based on expected load profiles and ambient temperature conditions. Verify that the required output voltage ranges align with the device's specified operational limits and that the I2C address conflicts are resolved within the system design.
Part Context
This device belongs to the DA9130 series of sub-PMICs designed for flexible and scalable power solutions. It complements other components in the Renesas portfolio by providing dedicated, high-current regulation for sensitive digital loads. The series emphasizes efficiency and size optimization through integrated power stages.
Replacement Considerations
Consult official substitution lists for verified alternatives such as the DA9131 or DA9132 series depending on current requirements. Ensure pin-to-pin compatibility and functional equivalence if replacing within an existing design without layout modifications.
