Product details
Overview
DA9130-08RT1 from Renesas Electronics is a high-performance, dual-phase synchronous buck DC-DC converter PMIC delivering up to 10 A output current at 0.3 V–1.9 V with ±1 % static voltage accuracy, 4 MHz switching frequency, and integrated power FETs - designed for CPU/GPU/DDR rails in SIPP modules and portable SoC systems.
For engineers reviewing the DA9130-08RT1 datasheet, DA9130-08RT1 pinout, DA9130-08RT1 application, or DA9130-08RT1 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in mobile and industrial power delivery, and confirmed alternative options for supply continuity and design flexibility.
Technical Context
The DA9130-08RT1 operates as a single-output, dual-phase buck converter with fully integrated high-side and low-side MOSFETs (RON_PMOS = 17–37 mΩ, RON_NMOS = 6–16 mΩ), supporting automatic phase shedding between 1- and 2-phase modes based on load current thresholds (ITHR_2PH_TO_1PH = 1.7 A, ITHR_1PH_TO_2PH = 2.25 A).
It implements remote sensing via differential FB1P/FB1N and FB2P/FB2N inputs, supports dynamic voltage control (DVC) via I²C or dedicated GPIO, and features programmable soft-start, thermal shutdown, cycle-by-cycle overcurrent protection, and FM+ I²C interface (up to 1 MHz) with configurable slave address.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V - compatible with single-cell Li-ion, USB PD, and multi-rail system supplies. |
| Output Voltage Range | 0.3 V to 1.9 V in 10 mV steps - enables precise core voltage scaling for modern CPUs/GPUs. |
| Max Output Current | 10 A continuous - delivered across two phases with 5 A per phase capability and peak transient support. |

Pinout & Package
DA9130-08RT1 is housed in a 24-pin FCQFN package (3.3 mm × 4.8 mm, wettable flanks) with exposed thermal pad for enhanced heat dissipation in high-power density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1, PVDD2 (Pins 1–2, 15–16) | Power Supply Input | High-current input rails for Phase 1 and Phase 2 - each rated for 5 A continuous, requiring low-impedance PCB routing. |
| LX1, LX2 (Pins 23–24, 17–18) | Switch Node Output | Phase 1 and Phase 2 buck switch nodes - connect directly to external inductors; require tight layout to minimize EMI. |
| FB1P/FB1N, FB2P/FB2N (Pins 4–5, 12–13) | Differential Feedback Inputs | Enable remote sensing for ±1 % accuracy - compensates for PCB trace IR drop in high-current paths. |

| AVDD / AGND (Pins 8–9) | Analog Power & Ground | Separate analog supply domain - isolates sensitive feedback and reference circuits from digital noise. |
| PGND (Pins 19–22) | Power Ground | High-current return path for both phases - must be connected to thermal pad and low-impedance ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase architecture with auto phase shedding | Reduces light-load quiescent current (IQ_PFM_2PH = 164 µA) while maintaining full 10 A capability at peak load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP8859GQ-Z (Monolithic Power Systems) | Single-phase 12 A solution; no integrated remote sensing; 2.5 MHz max switching frequency. | Lacks dual-phase efficiency optimization and differential feedback - less suitable for sub-1 V, high-accuracy DDR rails. | Preferred for cost-sensitive, lower-current applications where phase shedding and remote sensing are not required. |
| TPS62480RHAT (Texas Instruments) | Dual-phase 12 A with PMBus interface; requires external current-sense resistors; larger 5 mm × 5.5 mm QFN package. | Supports telemetry and advanced diagnostics but increases BOM count and layout complexity vs DA9130-08RT1's integrated sensing. | Chosen when system-level power monitoring and firmware-updatable parameters are mandatory. |
Compared with MP8859GQ-Z and TPS62480RHAT, DA9130-08RT1 uniquely combines 4 MHz operation, integrated remote sensing, and wettable-flank FCQFN in a 3.3 mm × 4.8 mm footprint - enabling higher power density and tighter voltage regulation without external components.

FAQ
What is the maximum output current supported by the DA9130-08RT1?
The DA9130-08RT1 delivers up to 10 A continuous output current using its dual-phase architecture, with each phase rated for 5 A. Peak transient capability exceeds this rating for short durations, and phase shedding dynamically adjusts conduction to optimize efficiency across load ranges - all verified in the R16DO0058EJ0301 datasheet. The DA9130-08RT1 achieves this without external FETs thanks to fully integrated power stages.
Does the DA9130-08RT1 support remote voltage sensing?
Yes, the DA9130-08RT1 supports true differential remote sensing via dedicated FB1P/FB1N and FB2P/FB2N pins, enabling ±1 % output voltage accuracy even with significant PCB trace resistance. This feature is explicitly documented in Table 8 and Section 5.1.3 of the DA9130-08RT1 datasheet and is essential for maintaining regulation integrity in high-current CPU/GPU/DDR applications.
What package type and dimensions does the DA9130-08RT1 use?
The DA9130-08RT1 uses a 24-pin FCQFN package measuring 3.3 mm × 4.8 mm with wettable flanks and an exposed thermal pad - detailed in Figure 14 and Section 9 of the official datasheet. This package supports automated optical inspection (AOI) and provides superior thermal performance for high-power-density designs, unlike standard QFN variants without wettable flanks.
Can the DA9130-08RT1 operate with a 3.3 V input supply?
Yes, the DA9130-08RT1 operates across a 2.8 V to 5.5 V input range, making 3.3 V fully compliant per Table 5 (Recommended Operating Conditions). At 3.3 V input, it sustains full 10 A output capability down to 0.3 V, with efficiency exceeding 85 % in PWM mode (Figure 6), and supports seamless transition into PFM mode for ultra-low IQ operation at light loads.
How is dynamic voltage control (DVC) implemented on the DA9130-08RT1?
DVC on the DA9130-08RT1 is implemented either via direct I²C register writes (using FM+ interface) or through a dedicated programmable GPIO pin, allowing real-time adjustment of output voltage in 10 mV steps - as specified in Section 5.1.3 and Table 8. This enables synchronized voltage scaling with processor DVFS states, reducing power consumption during idle modes without software intervention. The DA9130-08RT1 executes DVC transitions with controlled slew rate to prevent rail collapse.
