Product details
Overview
DA9130-XXRT1-AT from Renesas Electronics is a high-performance, AEC-Q100 Grade 2 qualified dual-phase buck DC-DC converter PMIC designed for automotive CPU/GPU/DDR power delivery. It delivers up to 10 A output current across a 0.3 V–1.9 V programmable output voltage range, operates from 2.8 V–5.5 V input, and integrates fully synchronous FETs in a 24-pin FCQFN (3.3 mm × 4.8 mm) package with wettable flanks.
For engineers reviewing the DA9130-XXRT1-AT datasheet, DA9130-XXRT1-AT pinout, DA9130-XXRT1-AT application, or DA9130-XXRT1-AT equivalent, key selection considerations include its 4 MHz switching frequency, ±1 % static output voltage accuracy, remote sensing capability, I²C-compatible FM+ interface, and integrated over-temperature/over-current protection for ADAS and infotainment power rails.
Technical Context
The DA9130-XXRT1-AT implements a single-channel, dual-phase synchronous buck topology with independent phase control and cycle-by-cycle current limiting. Its 4 MHz fixed-frequency PWM operation enables compact 220 nH inductors per phase and supports dynamic voltage scaling via register-controlled DVC or dedicated GPIO-driven mode transitions.
It features integrated analog feedback paths (FB1P/FB1N, FB2P/FB2N), remote-sense-capable differential inputs, and configurable GPIOs (CONF/GPIO0, GPIO1, GPIO2, SCL/GPIO3, SDA/GPIO4) that support I²C address selection, power-good indication, and DVC trigger functions - all operating across –40 °C to +105 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V - compatible with automotive 3.3 V and 5.0 V bias rails without external regulators. |
| Output Voltage Range | 0.3 V to 1.9 V in 10 mV steps - supports low-voltage SoC cores and DDR memory rails with fine-grained DVS control. |
| Max Output Current | 10 A total (5 A per phase) - enables high-current digital load powering with dual-phase interleaving to reduce ripple and thermal stress. |
| Switching Frequency | 4 MHz nominal - allows use of ultra-small 220 nH inductors and minimizes output capacitor count (20 µF typical). |
| Output Accuracy | ±1 % (static, VOUT ≥ 1 V) - ensures stable core voltage under line/load transients in automotive ECU applications. |
| Protection Features | Integrated over-temperature shutdown, cycle-by-cycle over-current limiting, and power-good monitoring - eliminates need for external fault-sensing circuitry. |
| Interface | I²C-compatible FM+ (1 MHz max) - enables real-time register access for DVC, status reporting, and multi-device addressing via CONF pin. |
| Ambient Temp Range | –40 °C to +105 °C - validated for under-hood and center-console automotive environments per AEC-Q100 Grade 2. |
Pinout & Package
DA9130-XXRT1-AT is housed in a 24-pin FCQFN package (3.3 mm × 4.8 mm, 0.5 mm pitch) with wettable flanks for automated optical inspection. The package supports high-power dissipation (θJA = 21.21 °C/W) and meets MSL3 moisture sensitivity requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1, PVDD2 (Pins 1–2, 15–16) | Power supply inputs | Dedicated 5 A-rated inputs per channel - decouples phase supply paths to minimize cross-talk and improve transient response. |
| LX1, LX2 (Pins 23–24, 17–18) | Buck switch node outputs | High-current (5 A per phase) switched nodes - require low-inductance layout to suppress EMI and gate ringing. |
| FB1P/FB1N, FB2P/FB2N (Pins 5, 4, 12, 13) | Differential remote sense inputs | Enable Kelvin connection to load - maintains ±1 % regulation accuracy despite PCB trace IR drop up to 100 mΩ. |
| SCL/GPIO3, SDA/GPIO4 (Pins 3, 6) | I²C bus interface / GPIO | FM+-compliant bidirectional lines - support 1 MHz clock rate and configurable pull-up for multi-device bus arbitration. |
| CONF/GPIO0 (Pin 10) | Configuration input / GPIO | Resets I²C slave address at power-on - allows up to four DA9130-XXRT1-AT devices on same bus without address conflict. |
| IC_EN (Pin 7) | Global enable input | Active-high logic control - initiates soft-start sequence and enables both phases only when asserted above 1.4 V. |
| PGND (Pins 19–22) | Power ground return | Separate low-impedance ground plane connection - isolates high-di/dt switching currents from analog reference paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase interleaved buck | Reduces input/output ripple by >70 % vs. single-phase 10 A design - lowers EMI filter component count and size. |
| Programmable soft-start | Configurable ramp time (1–32 ms) - prevents input rail collapse during cold cranking in automotive start-stop systems. |
| Dynamic voltage control (DVC) | Real-time VOUT adjustment via I²C register write or GPIO edge - cuts CPU core power by up to 40 % during idle states. |
| Fully integrated power stage | No external high-side/low-side FETs or Schottky diodes required - reduces BoM count by 8 components and saves 218 mm² PCB area. |
| Remote sensing with differential inputs | Compensates for up to 100 mV IR drop across PCB traces - maintains regulation accuracy even with long, narrow power delivery paths. |
| AEC-Q100 Grade 2 qualification | Validated for operation from –40 °C to +105 °C ambient - certified for safety-critical ADAS camera modules and cluster displays. |

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 |
|---|---|---|---|
| MPQ8633BGLE-Z | 4.5 V–18 V input, 0.6 V–5.5 V output, 12 A max, 750 kHz–1.5 MHz adjustable fSW - lacks remote sensing and AEC-Q100 Grade 2 rating. | Targeted at industrial motor drives; not qualified for automotive cabin or ADAS zones. | Choose for non-automotive 12 V systems requiring higher VIN tolerance and adjustable frequency - not drop-in for DA9130-XXRT1-AT. |
| TPS65917B1RSLR | Multi-rail PMIC with 3 buck channels (up to 3 A each), I²C, AEC-Q100 Grade 2 - no single 10 A dual-phase channel; smaller 0.6 V–1.52 V VOUT range. | Designed for infotainment SoC companion power - insufficient current for GPU or high-end CPU cores. | Choose when consolidating multiple lower-current rails (RTC, LDOs, buck2/buck3) - requires redesign if replacing DA9130-XXRT1-AT's 10 A capability. |
Compared with MPQ8633BGLE-Z and TPS65917B1RSLR, the DA9130-XXRT1-AT uniquely combines AEC-Q100 Grade 2 qualification, 10 A dual-phase capability, 4 MHz fixed-frequency operation, and differential remote sensing - making it the only option among the three qualified for safety-critical, high-current automotive core rail applications.

FAQ
What is the maximum output current capability of the DA9130-XXRT1-AT?
The DA9130-XXRT1-AT delivers up to 10 A total output current using dual-phase interleaved operation - 5 A per phase - with integrated FETs rated for continuous 5 A per channel. This is confirmed in the datasheet's Table 8 (Dual-Phase Buck Electrical Characteristics) under IMAX, and applies across the full –40 °C to +105 °C ambient temperature range with appropriate PCB thermal design.
Does the DA9130-XXRT1-AT support remote voltage sensing?
Yes, the DA9130-XXRT1-AT supports true differential remote sensing via dedicated FB1P/FB1N and FB2P/FB2N pins. This allows Kelvin connections directly at the load to compensate for PCB trace resistance, maintaining ±1 % output voltage accuracy even with up to 100 mΩ of path resistance - a feature explicitly documented in the "Benefits" section and Figure 1 of the datasheet.
What communication interface does the DA9130-XXRT1-AT use, and what is its speed?
The DA9130-XXRT1-AT uses an I²C-compatible interface compliant with Fast Mode Plus (FM+) specifications, supporting clock rates up to 1 MHz. Pin assignments SCL/GPIO3 and SDA/GPIO4 are configurable as standard I²C lines, and the device supports multiple slave addresses via the CONF/GPIO0 pin - details are specified in Section 5.4 and Table 11 of the datasheet.
Is the DA9130-XXRT1-AT qualified for automotive applications?
Yes, the DA9130-XXRT1-AT is AEC-Q100 Grade 2 qualified for automotive applications, with guaranteed operation from –40 °C to +105 °C ambient temperature. This qualification is stated on page 1 of the datasheet under "Key Features" and verified in Section 3.3 (Recommended Operating Conditions) and Table 6 (Package Ratings).
What is the switching frequency of the DA9130-XXRT1-AT, and why is it significant?
The DA9130-XXRT1-AT operates at a nominal 4 MHz switching frequency, as specified in Table 8 (Dual-Phase Buck Electrical Characteristics). This high frequency enables use of ultra-small 220 nH inductors and minimal output capacitance (20 µF), reducing solution size to 218 mm² - a critical advantage for space-constrained automotive modules like ADAS cameras and digital clusters.
