Product details
Overview
DA9141-XXF71-A from Renesas Electronics is an AEC-Q100 Grade 1 automotive DC-DC buck converter delivering 25 A continuous and 40 A peak output current across four synchronized phases, with 0.5 V–1.3 V programmable output voltage, ±1% static accuracy, and 4 MHz nominal switching frequency. It integrates power FETs, supports dynamic voltage control (DVC) via I²C or GPIO, and targets high-current processor rails in ADAS and infotainment systems.
For engineers reviewing the DA9141-XXF71-A datasheet, DA9141-XXF71-A pinout, DA9141-XXF71-A application, or DA9141-XXF71-A equivalent, key selection considerations include quad-phase current capability, remote differential sensing (FBP/FBN), I²C FM+ interface (1 MHz), integrated thermal/overcurrent protection, and 60-ball FC-BGA (4.5 mm × 7 mm) packaging for automotive power delivery.
Technical Context
The DA9141-XXF71-A implements a four-phase interleaved synchronous buck architecture with per-phase 110 nH inductors and integrated high-side/low-side MOSFETs. Its digital core enables phase shedding, soft-start ramp control, and real-time DVC adjustment to match processor DVFS requirements.
Control is executed via an I²C FM+ interface (up to 1 MHz) with configurable slave address and five programmable GPIOs (including CONF/GPIO0 and SCL/SDA dual-function pins). Supervision includes ±5% load transient response, junction temperature monitoring, and autonomous over-temperature shutdown at TJ ≥ 150 °C.
Key Specifications

| Interface | I²C FM+ (1 MHz) - provides fast register access for dynamic voltage scaling and fault logging in real time. |
| Thermal Protection | Junction shutdown at 150 °C - autonomous thermal management eliminates need for external thermal sensors or host polling. |
| Package | 60-ball FC-BGA, 4.5 mm × 7 mm, 0.65 mm pitch - optimized for high-current PCB routing and automotive thermal cycling reliability. |
Pinout & Package
DA9141-XXF71-A uses a 60-ball flip-chip ball grid array (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm pitch. The layout separates noisy power grounds (PGND1–PGND4), analog ground (AGND), and dedicated power rails (PVDD1–PVDD4) to minimize coupling between switching nodes (LX1–LX4) and sensitive analog feedback paths (FBP/FBN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1–PVDD4 | Power supply input per phase | Each powers one buck phase's high-side/low-side FET driver; requires local 10 µF decoupling to AVDD rail. |
| LX1–LX4 | Switch node output per phase | Connects directly to 110 nH inductor; carries high di/dt current-requires short, low-inductance PCB traces. |
| PGND1–PGND4 | Power ground return per phase | Dedicated thermal and current return path per phase; must be connected to solid internal ground plane. |
| FBP / FBN | Differential feedback sense inputs | Enables remote sensing at point-of-load; FBP connects to VOUT, FBN to local GND-rejects IR drop errors. |
| SCL/GPIO3 / SDA/GPIO4 | I²C bus interface or GPIO | Configurable dual-function pins supporting standard I²C communication or general-purpose digital I/O. |
| CONF/GPIO0 | Configuration input or GPIO | Defines I²C slave address at power-up; also usable as programmable input/output after initialization. |
| IC_EN | Interface enable control | Activates internal bandgap, oscillator, and I²C controller; independent of power stage enable. |
| GPIO1–GPIO2 | General-purpose I/O | Programmable as input, open-drain output, or interrupt source; supports system-level status signaling. |
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 dedicated GPIO pin-critical for processor DVFS. |
| Integrated power FETs | Eliminates need for external MOSFETs or Schottky diodes-reduces BOM count and layout complexity. |
| Remote differential sensing (FBP/FBN) | Compensates for PCB trace resistance, ensuring ±1% regulation accuracy at the actual load point-not at IC pins. |
| Programmable soft-start | Controls inrush current during power-up by limiting dV/dt on VOUT-prevents input rail collapse and system reset. |
| AEC-Q100 Grade 1 qualification | Validated for operation from −40 °C to +125 °C ambient, meeting automotive reliability and lifetime requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ8633BGLE-10-Z | Single-phase, 30 A peak, 2.7–16 V input, no integrated DVC or remote sensing. | Targeted at simpler ECUs without DVFS; lacks differential feedback and I²C programmability. | Choose when cost and board area are prioritized over adaptive voltage control and precision load regulation. |
| TPS65917B1RSLR | Multi-rail PMIC (not standalone buck); 2 A max per buck channel; supports I²C but no quad-phase topology. | Designed for companion power in infotainment SoCs-not suitable for >10 A core rails. | Choose only for auxiliary rail generation in systems already using TPS65917; not a functional replacement for DA9141-XXF71-A's primary core supply role. |
Compared with MPQ8633BGLE-10-Z and TPS65917B1RSLR, DA9141-XXF71-A uniquely combines quad-phase 40 A peak capability, integrated DVC, and remote differential sensing-enabling compact, high-reliability core power for next-gen automotive AI and ADAS SoCs where dynamic efficiency and point-of-load accuracy are non-negotiable.

FAQ
What is the maximum output current rating for DA9141-XXF71-A?
The DA9141-XXF71-A delivers 25 A continuous output current and supports up to 40 A peak current in burst mode. This rating is achieved through its quad-phase interleaved architecture, which distributes thermal and electrical stress across four parallel power stages while maintaining tight regulation via integrated current balancing and remote sensing.
Does DA9141-XXF71-A support dynamic voltage scaling (DVS) or dynamic voltage control (DVC)?
Yes, DA9141-XXF71-A supports dynamic voltage control (DVC) via either I²C register writes or a dedicated programmable GPIO pin. This allows real-time adjustment of the output voltage in 10 mV steps to match processor load states-enabling energy savings in AI engines and navigation SoCs without requiring host software intervention for every voltage change.
What package type and dimensions does DA9141-XXF71-A use?
DA9141-XXF71-A uses a 60-ball flip-chip ball grid array (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm pitch. The package features separate power and analog ground balls, dedicated LX and PVDD balls per phase, and optimized thermal vias-designed for automotive-grade thermal cycling and high-current PCB routing in constrained spaces.
Is DA9141-XXF71-A qualified for automotive applications?
Yes, DA9141-XXF71-A is fully AEC-Q100 qualified for Grade 1 operation (−40 °C to +125 °C ambient), including stress testing for temperature cycling, humidity, and mechanical shock. It meets automotive reliability standards for navigation systems, telematics, and ADAS applications where long-term field stability and zero-defect operation are mandatory.
How does DA9141-XXF71-A implement remote voltage sensing?
DA9141-XXF71-A implements remote differential sensing using dedicated FBP (positive feedback) and FBN (negative feedback) pins. FBP connects directly to the load's VOUT node, and FBN connects to the load's local ground-allowing the IC to regulate voltage precisely at the point of load, compensating for IR drop across PCB traces and ensuring ±1% accuracy regardless of board layout parasitics.
