Product details
Overview
DA9141-XXF71 from Renesas Electronics is a 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 infotainment and ADAS power rails.
For engineers reviewing the DA9141-XXF71 datasheet, DA9141-XXF71 pinout, DA9141-XXF71 application, or DA9141-XXF71 equivalent, this page provides verified pin functions, dynamic voltage control (DVC) implementation details, remote sensing configuration, I²C FM+ interface timing, and thermal derating curves for high-reliability automotive designs.
Technical Context
The DA9141-XXF71 implements four interleaved buck phases with independent LX nodes and shared PVDD/PGND rails to reduce input/output ripple and improve transient response. Its digital core supports real-time DVC via register writes or dedicated GPIO, enabling adaptive voltage scaling synchronized with processor load states.
It integrates full protection circuitry-including overcurrent detection per phase, junction temperature monitoring with warning/critical thresholds, and soft-start ramp control-without external sensing components. The 60-ball FC-BGA package (4.5 mm × 7 mm, 0.65 mm pitch) supports high-current routing with 10,000 mA drive capability on all PVDD and LX pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage | 2.8 V to 5.5 V - supports direct connection to automotive 3.3 V or 5 V bias rails without pre-regulation. |
| Output Voltage Range | 0.5 V to 1.3 V in 10 mV steps - enables precise core voltage tuning for AI accelerators and SoCs. |
| Continuous/Peak Current | 25 A / 40 A - sustains full load across all four phases with thermal derating up to 125 °C ambient. |
| Switching Frequency | 4 MHz nominal - allows use of compact 110 nH inductors and reduces output capacitor count. |
| Output Accuracy | ±1% static - achieved via differential remote sensing (FBP/FBN) at point-of-load for stable rail regulation. |
| I²C Interface | FM+ compatible (1 MHz max) - supports multi-device addressing via configurable GPI and programmable slave address register. |
| Thermal Resistance | θJA = 9.6 °C/W with heatsink - enables >6 W power dissipation at 85 °C ambient before derating begins. |
| Protection Features | Per-phase OCP, thermal shutdown, and voltage supervision - eliminates need for external fault-detection circuitry. |
Pinout & Package
DA9141-XXF71 uses a 60-ball Fine-Pitch Chip Scale Ball Grid Array (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm ball pitch. The layout separates noisy power grounds (PGND1–PGND4), analog ground (AGND), and quiet supply rails (AVDD) to minimize coupling in high-speed digital power applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1–PVDD4 | Power supply input for each buck phase | Each rated for 10 A continuous; requires local 10 µF ceramic decoupling and shared AVDD connection. |
| LX1–LX4 | Phase switch node outputs | Connect to 110 nH inductors; high di/dt paths demand short, wide traces and tight loop area with PGND return. |
| PGND1–PGND4 | Power ground return for each phase | Must be connected to low-impedance thermal pad under package; separate from AGND to avoid noise injection. |
| FBP / FBN | Differential feedback sense inputs | Enable remote sensing: FBP connects to VOUT at load, FBN connects to GND at same location for ±1% accuracy. |
| SCL/GPIO3 / SDA/GPIO4 | I²C bus interface or GPIO | Configurable as FM+ I²C (1 MHz) or general-purpose I/O; internal pull-ups enabled only when used as I²C. |
| CONF/GPIO0 | Configuration select or GPIO | Hardwired at startup to set I²C address; can be reconfigured as GPIO after initialization via register write. |
| IC_EN | Control interface enable | Active-high signal that powers up bandgap reference, oscillator, and I²C logic; must be asserted before communication. |
| GPIO1–GPIO2 | General-purpose I/O | Programmable as input/output with 10 mA drive; support interrupt generation and status reporting via register-mapped control. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-phase interleaving | Reduces input RMS current by ~50% and output voltage ripple amplitude by ~75% versus single-phase design. |
| Dynamic Voltage Control (DVC) | Enables real-time VOUT adjustment via I²C register write or dedicated GPIO edge trigger for CPU/GPU DVFS sequences. |
| Integrated MOSFETs | Eliminates need for 8 external high-side/low-side FETs and associated gate drivers, reducing BOM count and layout complexity. |
| Remote differential sensing | Compensates for PCB trace IR drop up to 50 mV, maintaining ±1% regulation at point-of-load under full 25 A load. |
| Configurable soft-start | Programmable ramp time prevents inrush current spikes during power-up, protecting upstream converters and input capacitors. |
| AEC-Q100 qualification | Available in automotive-grade variant (DA9141-XXF71-A) meeting Grade 2 (-40 °C to +105 °C) reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ8633BGLE-Z | Single-chip 30 A peak, 3-phase controller with external FETs; no integrated DVC GPIO; 2.5 MHz max switching frequency. | Lacks native remote sensing and requires external current-sense amplifiers for per-phase OCP; suited for cost-sensitive industrial designs. | Select when board space allows discrete FET placement and DVC is implemented externally via MCU GPIO. |
| TPS546D24RSAR | 40 A peak, 4-phase, PMBus-compatible controller with integrated FETs; supports 0.5–2.0 V output; 1.5–2.2 MHz programmable frequency. | Uses PMBus instead of I²C FM+; lacks dedicated CONF pin for address selection; higher minimum output voltage limits low-Vdd AI core use. | Prefer when PMBus ecosystem integration and telemetry logging are required over automotive-grade thermal robustness. |

FAQ
What is the maximum supported output voltage for DA9141-XXF71?
The DA9141-XXF71 supports an output voltage range of 0.5 V to 1.3 V, programmable in 10 mV increments via its I²C interface or hardware configuration pins. This range is optimized for modern low-voltage AI and application processor cores. Operation outside this range is not supported and may result in regulation failure or device protection activation.
Does DA9141-XXF71 require external MOSFETs?
No, DA9141-XXF71 integrates all high-side and low-side power MOSFETs for its four buck phases, eliminating the need for external FETs or Schottky diodes. This integration reduces solution size, simplifies layout, and improves efficiency by optimizing gate drive timing and minimizing parasitic losses inherent in discrete implementations.
How does the dynamic voltage control (DVC) function work on DA9141-XXF71?
DA9141-XXF71 implements DVC through two methods: direct register writes via its I²C FM+ interface or edge-triggered updates using a dedicated GPIO pin. When activated, DVC adjusts the output voltage in real time to match processor load states-enabling energy savings during low-activity periods and stable operation during burst workloads without software intervention.
What package type and dimensions does DA9141-XXF71 use?
DA9141-XXF71 uses a 60-ball Fine-Pitch Chip Scale BGA (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm ball pitch. The package features separate power ground (PGND1–PGND4) and analog ground (AGND) balls, plus dedicated thermal vias under the die pad to support >6 W dissipation with appropriate PCB copper and heatsinking.
