DA9130-XXRT1-A

Overview

The DA9130-XXRT1-A is a high-efficiency, automotive-grade, single-channel step-down DC/DC converter with integrated switching FETs delivering up to 10A output current. It operates within an input voltage range of 2.5V to 5.5V and supports output voltages from 0.3V to 1.9V. The device features a nominal switching frequency of 4MHz, ±1% static accuracy, and ±5% dynamic accuracy. It includes I2C-compatible interface (FM+), programmable GPIOs, remote sensing, and dynamic voltage control. Safety features include output undervoltage/overvoltage protection, input undervoltage protection, and two-step over-temperature protection. It is qualified to AEC-Q100 Grade 2 standards for ambient temperatures ranging from -40°C to +105°C.

Feature Summary

• High-efficiency buck conversion exceeding 90% efficiency reduces thermal design challenges in high-current applications.
• Fully integrated switching FETs eliminate the need for external FETs or Schottky diodes.
• Remote sensing ensures high accuracy and supports various PCB layout schemes without performance degradation.
• Dynamic Voltage Control (DVC) adapts output voltage based on load conditions to improve efficiency during low-power modes.

Applications

• Automotive infotainment systems
• Navigation systems
• Telematics units
• Advanced Driver Assistance Systems (ADAS)
• High-performance automotive processing systems

Procurement Notes

Verify the specific suffix 'XX' in the part number DA9130-XXRT1-A against official Renesas documentation to confirm exact output voltage configuration and package variant. Ensure compatibility with AEC-Q100 Grade 2 requirements if used in automotive environments. Confirm availability status as supply constraints may apply to this component series.

Selection Notes

Select this component for applications requiring a single high-current rail up to 10A with strict thermal management needs. It is suitable for standard 5V supplies or USB power sources. Consider the 3.3mm x 4.8mm 24-pin FC-QFN wettable flank package for space-constrained designs. Verify that the required output voltage falls within the 0.3V to 1.9V range or requires an external resistor divider for higher voltages.

Part Context

The DA9130-XXRT1-A belongs to the DA913X-A family of flexible, scalable, and reliable automotive sub-PMICs from Renesas. This family enables tailored 'Exact-Fit' power solutions for complex automotive electronics. The DA9130-A specifically offers a single-channel configuration with 10A capability, complementing the dual-channel variants like the DA9131-A and DA9132-A which offer lower per-channel currents.
