Overview
The DA9130-XXRT1 is a dual-phase, high-efficiency DC-DC converter from the Renesas DA9130 series. It integrates two synchronous buck converters capable of delivering up to 10A per phase. The device features an I2C-compatible interface for configuration and monitoring. Output voltage selection is configurable via General Purpose Inputs (GPI), with specific variants supporting selectable outputs such as 0.8V/0.85V or 1.0V/1.05V. The component operates within a standard industrial temperature range and utilizes a compact FC-QFN package.
Feature Summary
- Dual-phase architecture providing high current density and reduced input/output ripple
- Integrated switching FETs eliminating the need for external power transistors
- Configurable output voltage selection via programmable General Purpose Inputs (GPI)
- I2C communication interface for dynamic control and system monitoring
Applications
- High-performance processing systems requiring efficient power delivery
- Automotive infotainment and telematics units
- Advanced Driver Assistance Systems (ADAS) power rails
- Industrial control boards and networking equipment
Procurement Notes
Verify exact suffix specifications when ordering, as they determine fixed output voltage levels (e.g., -08RT1 vs -10RT1). Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure compatibility with existing I2C bus addresses and GPI configurations during integration planning.
Selection Notes
Select this component for applications demanding high current capacity in a small footprint. Compare against lower-current alternatives like the DA9131 or DA9132 if load requirements are below 5A or 3A respectively. Verify that the required output voltage matches the specific suffix variant available. Consider thermal management solutions based on the total power dissipation of the dual-phase design.
Part Context
The DA9130 belongs to Renesas' flexible PMIC family designed for automotive and industrial sub-systems. It complements other devices in the series by offering higher current capabilities compared to the 5A DA9131 and 3A DA9132 models. This positioning makes it suitable for powering complex processors where space and efficiency are critical constraints.
Replacement Considerations
Direct substitutes include other DA9130 variants with different fixed output voltages (e.g., DA9130-08RT1, DA9130-10RT1). For lower current needs, consider the DA9131 or DA9132 families, though pinouts and performance characteristics will differ significantly.
