Product details
Overview
DA9141-XXF72 from Renesas Electronics is a high-efficiency, quad-phase synchronous buck DC-DC converter delivering 25 A continuous and 40 A peak output current, with 0.5 V–1.3 V programmable output voltage, 4 MHz switching frequency, and integrated FETs for automotive-grade power delivery to AI engines and ADAS processors.
For engineers reviewing the DA9141-XXF72 datasheet, DA9141-XXF72 pinout, DA9141-XXF72 application, or DA9141-XXF72 equivalent, this page provides verified technical context on dynamic voltage control (DVC), remote sensing accuracy, I²C FM+ interface timing, thermal derating behavior, and phase-shedding efficiency optimization under load transients.
Technical Context
The DA9141-XXF72 implements a four-phase interleaved synchronous buck architecture with per-phase 110 nH inductors and 220 µF total output capacitance, enabling ripple cancellation and scalable current handling up to 40 A peak. Its digital core supports real-time DVC via register writes or dedicated GPIO, allowing adaptive supply voltage adjustment synchronized to processor load states.
Thermal management integrates junction temperature monitoring with programmable warning/critical thresholds and automatic shutdown at 150 °C. The 60-ball FC-BGA package (4.5 mm × 7 mm, 0.65 mm pitch) separates noisy power grounds (PGND1–4) from quiet analog ground (AGND) and uses differential feedback (FBP/FBN) for ±1% static output voltage accuracy at point-of-load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage | 2.8 V to 5.5 V - supports wide-range automotive battery and intermediate rail inputs without external pre-regulation. |
| Output Voltage | 0.5 V to 1.3 V in 10 mV steps - enables precise core voltage tuning for modern SoCs and AI accelerators. |
| Output Current | 25 A continuous / 40 A peak - sustains burst workloads in ADAS vision processing and infotainment GPU operation. |
| Switching Frequency | 4 MHz nominal - allows compact 110 nH inductors and reduces output filter footprint versus lower-frequency converters. |
| Voltage Accuracy | ±1% static - achieved via remote-sense differential feedback (FBP/FBN), minimizing IR drop impact across PCB traces. |
| Interface | I²C FM+ (1 MHz) - enables fast configuration and telemetry readback of voltage, current, and temperature supervision registers. |
| Protection | Integrated over-temperature, over-current, and thermal shutdown - eliminates need for external fault-detection circuitry. |
| Package | 60-ball FC-BGA, 4.5 mm × 7 mm, 0.65 mm pitch - optimized for thermal dissipation and high-density automotive PCB layouts. |
Pinout & Package
DA9141-XXF72 uses a 60-ball fine-pitch flip-chip ball grid array (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm pitch. Power integrity is enforced by dedicated PVDD1–4 and PGND1–4 balls per phase, while analog stability relies on isolated AVDD, AGND, FBP, and FBN connections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1–4 | Power supply input per phase | Each supplies one buck phase's high-side and low-side FETs; requires local 10 µF decoupling to AVDD. |
| LX1–4 | Switch node per phase | Connects to 110 nH inductor; high di/dt path requiring short, low-inductance routing to minimize EMI. |
| PGND1–4 | Power ground return per phase | Separate low-impedance return paths prevent coupling between phases and reduce ground bounce. |
| FBP / FBN | Differential feedback sense | Remote sensing at point-of-load improves regulation accuracy to ±1%; FBN connects to local GND near load. |
| SCL/GPIO3, SDA/GPIO4 | I²C interface or GPIO | FM+ compatible (1 MHz); configurable as general-purpose I/O when I²C not used. |
| CONF/GPIO0 | Configuration select / GPIO | Determines I²C slave address during power-up; also usable as programmable input after initialization. |
| IC_EN | Control interface enable | Activates internal bandgap, oscillator, and I²C logic; independent of power stage enable. |
| GPIO1–2 | General-purpose I/O | Configurable as input/output with 10 mA drive; supports interrupt signaling or status indication. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-phase interleaving | Reduces input/output ripple by factor of ~4 vs single-phase, easing EMI filtering and capacitor stress. |
| Dynamic voltage control (DVC) | Enables real-time VOUT adjustment via I²C register write or GPIO edge trigger-critical for DVFS in AI SoCs. |
| Programmable soft-start | Configurable ramp rate limits inrush current during rail activation, preventing input voltage droop or brownout. |
| Integrated supervision | Monitors output voltage, phase current (via RDS(on) sensing), and die temperature-all accessible via I²C. |
| AEC-Q100 qualification | Available in automotive-grade variant (DA9141-XXF72-A) meeting Grade 2 (-40 °C to +105 °C ambient). |
| 60-ball FC-BGA layout | Optimized thermal path with exposed thermal pad (connected to AGND) and separate power/analog ground domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, multi-phase buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2965A from Monolithic Power Systems | 6-phase, 40 A continuous, 0.3–1.52 V output, 600 kHz–1.2 MHz programmable frequency; no integrated DVC GPIO. | Targets server/cloud AI accelerators; lacks AEC-Q100 qualification and remote-sense differential feedback. | Preferred where higher phase count and wider VOUT range outweigh automotive compliance needs. |
| TPS546D24A from Texas Instruments | Single-chip 60 A peak, 4-phase controller with external FETs; supports PMBus 1.3, not I²C FM+; 0.5–2.0 V output. | Used in industrial computing and telecom; requires external MOSFETs and Schottky diodes, increasing BOM count. | Chosen when system-level flexibility (e.g., custom FET selection, higher voltage margin) is prioritized over integration. |
Compared with MP2965A and TPS546D24A, DA9141-XXF72 delivers tighter output accuracy (±1% vs ±1.5%), smaller solution size (180 mm² vs >250 mm²), and native automotive qualification-making it optimal for space-constrained, safety-critical ADAS and infotainment platforms.

FAQ
What is the maximum continuous output current supported by the DA9141-XXF72?
The DA9141-XXF72 supports 25 A continuous output current across its four interleaved phases. This rating assumes proper thermal management-including use of a heatsink, adherence to JEDEC 2S2P board guidelines, and ambient temperatures ≤85 °C. At higher ambient temperatures, derating applies per the datasheet's power derating curve. The DA9141-XXF72 also sustains 40 A peak current for short durations typical of AI workload bursts.
Does the DA9141-XXF72 require external MOSFETs or diodes?
No, the DA9141-XXF72 integrates all high-side and low-side synchronous FETs internally, eliminating the need for external MOSFETs or Schottky diodes. This integration reduces solution size, simplifies layout, and improves efficiency-especially at light-to-moderate loads where gate drive losses are minimized. The DA9141-XXF72 only requires external passive components: four 110 nH inductors and 220 µF total output capacitance.
How does dynamic voltage control (DVC) operate on the DA9141-XXF72?
Dynamic voltage control (DVC) on the DA9141-XXF72 allows real-time adjustment of the output voltage based on processor load-either via I²C register write (using FM+ interface) or through a dedicated GPIO edge trigger. This enables efficient DVFS in AI and application processors. The DA9141-XXF72 supports 10 mV voltage steps between 0.5 V and 1.3 V, with transition times under 10 µs when using GPIO-triggered DVC mode.
Is the DA9141-XXF72 qualified for automotive applications?
Yes-the DA9141-XXF72 is available in an AEC-Q100 qualified variant (designated DA9141-XXF72-A) rated for Grade 2 operation (−40 °C to +105 °C ambient). It includes built-in over-temperature protection, junction monitoring, and robust ESD ratings (2 kV HBM), meeting automotive reliability and safety requirements. The DA9141-XXF72 itself shares identical electrical and thermal specifications but may be supplied in non-automotive packaging unless explicitly ordered with -A suffix.
What package type and pin count does the DA9141-XXF72 use?
The DA9141-XXF72 uses a 60-ball flip-chip ball grid array (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm pitch. It features dedicated power (PVDD1–4), switch-node (LX1–4), and ground (PGND1–4) balls per phase, plus isolated analog supply (AVDD), ground (AGND), and differential feedback (FBP/FBN) pins. The DA9141-XXF72's pinout is documented in Figure 2 and Table 1 of the official Renesas datasheet R16DS0589EG0301.
