Product details
Overview
DA9130-XXRT2-A from Renesas Electronics is a dual-phase, 10 A automotive-grade DC-DC buck converter PMIC for CPU/GPU/DDR power rails in ADAS and infotainment systems. It delivers 0.3 V–1.9 V output at up to 10 A with ±1 % static voltage accuracy, 4 MHz switching frequency, and AEC-Q100 Grade 2 qualification.
For engineers reviewing the DA9130-XXRT2-A datasheet, DA9130-XXRT2-A pinout, DA9130-XXRT2-A application, or DA9130-XXRT2-A equivalent, key selection criteria include dual-phase current capability, I²C-compatible FM+ interface, remote sensing support, integrated over-temperature/over-current protection, and wettable-flank 24-pin FCQFN packaging for automotive thermal and reliability requirements.
Technical Context
The DA9130-XXRT2-A operates as a single-channel, dual-phase synchronous buck converter with fully integrated high-side and low-side FETs per phase. It supports dynamic voltage control (DVC) via register write or dedicated GPIO, enabling adaptive supply scaling during processor load transitions.
Its architecture includes independent feedback paths (FB1P/FB1N and FB2P/FB2N), programmable soft-start, cycle-by-cycle current limiting, and thermal shutdown triggered at junction temperatures exceeding 150 °C. The device uses a 4 MHz fixed-frequency PWM controller with phase shedding in auto mode to optimize light-load efficiency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4333-AEC1 | Single-phase 10 A, 2.5–6.5 V input, no DVC or remote sensing; 16-pin QFN. | Lacks dual-phase interleaving and differential feedback - higher output ripple and reduced load-transient immunity. | Choose when cost sensitivity outweighs need for DVC or remote sensing in non-critical clusters. |
| TPS659424-Q1 | Multi-rail PMIC with 3 buck channels (2× 6 A, 1× 3 A); I²C, AEC-Q100 Grade 1; 48-pin VQFN. | Higher integration but larger footprint and fixed channel assignment - less flexible for single-rail optimization. | Choose when multiple regulated rails (e.g., CPU + GPU + DDR) are needed in one package, accepting larger size and higher cost. |
Compared with MPQ4333-AEC1, DA9130-XXRT2-A provides superior transient response and voltage accuracy via dual-phase interleaving and remote sensing; compared with TPS659424-Q1, it offers smaller footprint and lower BOM cost for single-rail high-current applications where channel flexibility is unnecessary.

FAQ
What is the maximum supported output current for DA9130-XXRT2-A?
The DA9130-XXRT2-A delivers up to 10 A total output current using its dual-phase architecture - 5 A per phase - with integrated FETs and thermal derating validated across −40 °C to +105 °C ambient. This rating assumes proper PCB layout with adequate copper pour and airflow per Renesas' layout guidelines in R16DS0575EJ0300.
Does DA9130-XXRT2-A support dynamic voltage scaling (DVS) for CPU cores?
Yes, DA9130-XXRT2-A implements dynamic voltage control (DVC) that enables real-time output voltage adjustment based on processor load. DVC can be triggered either via I²C register writes or through a dedicated GPIO pin, allowing seamless integration with ARM big.LITTLE or similar DVFS-capable SoCs.
What package type and dimensions does DA9130-XXRT2-A use?
DA9130-XXRT2-A uses a 24-pin FCQFN package measuring 3.3 mm × 4.8 mm with wettable flanks. The package features exposed thermal pad and gull-wing-style side terminals for AOI compatibility - critical for automotive manufacturing traceability and solder joint reliability.
Is DA9130-XXRT2-A qualified for automotive applications?
Yes, DA9130-XXRT2-A is AEC-Q100 Grade 2 qualified, tested for operation from −40 °C to +105 °C ambient temperature, and designed for automotive infotainment, ADAS, telematics, and cluster applications. Its qualification includes HTOL, TC, ESD, and EM test coverage per AEC standards.
How does DA9130-XXRT2-A handle over-current and thermal faults?
DA9130-XXRT2-A integrates cycle-by-cycle current limiting and thermal shutdown with hysteresis. When over-current is detected, it disables the affected phase while maintaining operation on the other; at junction temperatures above 150 °C, it initiates full shutdown and asserts nIRQ. Fault status is readable via I²C registers without external components.
