DA9130-21RT1-A

Special Purpose Regulators Overview

The DA9130-21RT1-A is a dual-phase, synchronous step-down DC/DC converter manufactured by Renesas Electronics. It integrates two power stages capable of delivering up to 10A per channel from a single input voltage rail. The device supports an input voltage range of 2.5V to 5.5V and provides adjustable output voltages typically between 0.6V and 1.4V, configurable via I2C interface or General Purpose Inputs (GPI). Operating at a programmable switching frequency up to 2.2MHz, it utilizes a compact 24-pin FC-QFN package with wettable flanks for enhanced thermal performance and reliable soldering in high-density applications.

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'A' indicates automotive grade qualification against the official datasheet. Confirm the exact output voltage configuration associated with the '21' variant. Ensure compatibility with your system's I2C address settings and thermal management requirements before finalizing the procurement order.

Special Purpose Regulators Selection Notes

Select this component when dual isolated rails are required from a single source in automotive environments. Consider the 10A per channel capability for powering complex SoCs. Evaluate the thermal dissipation needs given the integrated FET design. Verify that the input voltage range aligns with the vehicle's battery architecture.

Special Purpose Regulators Part Context

This part belongs to the DA9130 series of high-efficiency buck converters designed for automotive sub-PMIC applications. It complements other Renesas power management solutions by offering scalable current delivery. The series is engineered to meet stringent automotive reliability standards while minimizing board space through high-frequency operation.

Special Purpose Regulators Replacement Considerations

Check for DA9130 variants with different current ratings or output configurations. Verify if non-automotive grades (DA9130 without -A) are acceptable for the application environment.
