Product details
Overview
DA9142-XXF71-A from Renesas Electronics is an AEC-Q100 Grade 1 automotive DC-DC buck converter delivering 13 A continuous and 20 A peak output current across dual-phase operation, with 0.5 V–1.3 V programmable output voltage, ±1% static accuracy, and 4 MHz switching frequency. It integrates high-side/low-side FETs, supports dynamic voltage control (DVC) via I²C or GPIO, and targets processor core rails in ADAS and infotainment systems.
For engineers reviewing the DA9142-XXF71-A datasheet, DA9142-XXF71-A pinout, DA9142-XXF71-A application, or DA9142-XXF71-A equivalent, key selection criteria include its dual-phase 20 A peak capability, remote-sense differential feedback (FBP/FBN), I²C FM+ interface with configurable slave address, integrated thermal/current protection, and 60-ball FC-BGA 4.5 mm × 7 mm package with 0.65 mm pitch.
Technical Context
The DA9142-XXF71-A implements a synchronous dual-phase buck topology with interleaved 180° phase shift to reduce input/output ripple and improve transient response. Its digital control loop uses internal voltage, current, and temperature supervision to enable adaptive DVC and robust fault handling without external sensing components.
It operates in PWM or auto mode with phase shedding, supports soft-start via register-controlled ramp rate, and features five programmable GPIOs-two dedicated (GPIO0–GPIO2), two multiplexed with I²C (SCL/GPIO3, SDA/GPIO4)-enabling flexible system integration and multi-device addressing on shared buses.
Key Specifications

Pinout & Package
DA9142-XXF71-A uses a 60-ball flip-chip BGA (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm pitch and integrated thermal pad. Ball assignment follows JEDEC MO-277, with dedicated PVDD/LX/PGND banks per phase, isolated analog ground (AGND), and dual-purpose I²C/GPIO pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1–PVDD4 | Power supply input for buck phases | Four independent 10 A-rated power inputs decoupled locally; connect to same source as AVDD for stability. |
| LX1, LX2 | Switch node outputs | Drive external 110 nH inductors per phase; require tight layout to minimize parasitic inductance and EMI. |
| PGND1–PGND4 | Power ground return | Low-impedance return paths for high di/dt currents; must be connected to solid internal ground plane. |
| FBP / FBN | Differential feedback sense | Enables remote sensing at point-of-load; FBP connects to VOUT, FBN to local GND for ±1% regulation accuracy. |
| SCL/GPIO3, SDA/GPIO4 | I²C interface or GPIO | FM+ capable (1 MHz); pull-up required externally; GPIO function enabled when I²C disabled via register. |
| CONF/GPIO0 | Configuration strap or GPIO | Configures I²C slave address during power-up; latched at reset; usable as general-purpose input post-configuration. |
| IC_EN | Control interface enable | Active-high signal enabling bandgap, oscillator, and I²C logic; independent of power stage enable. |
| GPIO1, GPIO2 | General-purpose I/O | 10 mA drive strength; support interrupt generation, status reporting, or sequencing control in system firmware. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| MPQ4436-AEC1 | Single-phase, 12 A continuous, 2.5–5.5 V input, 0.6–1.8 V output, no DVC or remote sense. | Lacks dual-phase current capability and dynamic voltage control; suitable only for lower-power SoCs without aggressive DVFS. | Select when cost sensitivity outweighs peak current headroom and DVC requirement. |
| TPS659424-Q1 | Multi-rail PMIC with 10 A buck (single-phase), I²C, integrated LDOs, but no remote sense or 20 A peak capability. | Provides auxiliary rails and sequencing but cannot replace DA9142-XXF71-A's 13 A/20 A core rail performance alone. | Select when system requires multiple regulated outputs and centralized power management-not standalone high-current core rail. |

FAQ
What is the maximum continuous output current rating for the DA9142-XXF71-A?
The DA9142-XXF71-A delivers 13 A continuous output current per device under recommended thermal conditions (with heatsink, TA ≤ 85°C). Its 20 A peak rating supports short-duration burst loads typical in AI accelerator and GPU applications. Derating applies above 85°C ambient, with 104.1 mW/°C reduction in max power dissipation.
Does the DA9142-XXF71-A support dynamic voltage control (DVC), and how is it implemented?
Yes, the DA9142-XXF71-A supports DVC through either I²C register writes (via FM+ interface) or direct GPIO assertion. This allows real-time adjustment of the output voltage in 10 mV steps based on processor load, reducing dynamic power consumption in navigation, AI, and infotainment SoCs without firmware intervention.
What package type and dimensions does the DA9142-XXF71-A use?
The DA9142-XXF71-A uses a 60-ball flip-chip BGA package measuring 4.5 mm × 7 mm with 0.65 mm pitch and integrated thermal pad. It complies with JEDEC MO-277 and features segregated power/ground ball groups to minimize noise coupling between phases and analog sections.
How does remote sensing work on the DA9142-XXF71-A, and why is it important?
The DA9142-XXF71-A implements remote sensing using differential FBP (positive) and FBN (negative) pins, connecting directly to the point-of-load and local GND respectively. This compensates for IR drop across PCB traces, ensuring ±1% output voltage accuracy at the SoC pins-not just at the converter output-critical for stable AI and processor operation.
Is the DA9142-XXF71-A qualified for automotive applications, and what standards does it meet?
Yes, the DA9142-XXF71-A is fully AEC-Q100 qualified for Grade 1 (-40°C to +125°C ambient), with validated performance across temperature, voltage, and lifetime stress tests.
