Product details
Overview
DA9141-XXF72-A from Renesas Electronics is an AEC-Q100 Grade 1 automotive DC-DC buck converter delivering 25 A continuous / 40 A peak output across four synchronized phases, with 0.5–1.3 V programmable output voltage, 4 MHz switching frequency, and integrated FETs. It serves as the primary core power supply for high-performance processors in ADAS and infotainment systems requiring precise dynamic voltage control and remote sensing.
For engineers reviewing the DA9141-XXF72-A datasheet, DA9141-XXF72-A pinout, DA9141-XXF72-A application, or DA9141-XXF72-A equivalent, key selection criteria include quad-phase current capability, I²C-compatible DVC interface, ±1% static output accuracy, thermal protection integration, and 60-ball FC-BGA package compatibility with automotive PCB layout constraints.
Technical Context
The DA9141-XXF72-A implements a four-phase interleaved synchronous buck architecture with per-phase 110 nH inductors and integrated high-side/low-side MOSFETs, enabling ripple cancellation and efficient 25 A continuous delivery. Its digital core supports real-time voltage supervision, load-line compensation, and phase shedding via I²C or dedicated GPIO-triggered DVC commands.
Operation relies on differential remote sensing (FBP/FBN) for point-of-load regulation, programmable soft-start to limit inrush, and autonomous over-temperature/over-current protection without external components. The FM+ I²C interface (up to 1 MHz) enables register-level control of output voltage, slew rate, fault masking, and GPIO configuration.

Key Features
| Feature | Design Value |
|---|---|
| Quad-phase interleaved buck | Reduces input/output ripple by factor of ~4 vs. single-phase, lowering EMI filter requirements and capacitor stress. |
| Dynamic Voltage Control (DVC) | Enables real-time output adjustment via I²C register write or GPIO edge trigger-critical for processor DVFS and power-state transitions. |
| Integrated MOSFETs | Eliminates need for 8 external power FETs and associated gate drivers, reducing BOM count and layout complexity. |
| Programmable soft-start | Configurable ramp time prevents input rail collapse during power-up, protecting upstream regulators and sequencing circuits. |

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-Z | 30 A continuous, 4-phase, 2.7–16 V input, no integrated remote sensing; requires external resistor divider for feedback. | Targeted at broader industrial/automotive input ranges but lacks differential sensing and AEC-Q100 Grade 1 certification. | Choose when input voltage exceeds 5.5 V or when cost-sensitive designs tolerate reduced output accuracy (±2%) and higher layout sensitivity. |
| TPS65917B1RSLR | Multi-rail PMIC with 2 A buck + LDOs; not a standalone 25 A solution-requires external high-current stage for core rail. | Designed for companion power management in TI Jacinto processors-not suitable as direct core rail replacement for DA9141-XXF72-A. | Choose only when integrating multiple low-current rails (DDR, I/O, RTC) alongside a separate high-current buck stage. |
Compared with MPQ8633BGLE-Z and TPS65917B1RSLR, the DA9141-XXF72-A uniquely combines AEC-Q100 Grade 1 qualification, integrated differential remote sensing, and true 25 A continuous quad-phase capability in a single 4.5 mm × 7 mm FC-BGA-enabling smaller, more robust power delivery for next-gen automotive AI processors without external sensing or phase management.
