Product details
Overview
DA9142-XXF72 from Renesas Electronics is an AEC-Q100 Grade 1 automotive DC-DC buck converter with dual-phase operation, delivering 13 A continuous and 20 A peak output current, 4 MHz switching frequency, and ±1% static output voltage accuracy across 0.5 V–1.3 V output range. It integrates high-side/low-side FETs, supports dynamic voltage control (DVC) via I²C or GPIO, and is used in ADAS domain controllers requiring precise rail sequencing and load-point regulation.
For engineers reviewing the DA9142-XXF72 datasheet, DA9142-XXF72 pinout, DA9142-XXF72 application, or DA9142-XXF72 equivalent, key selection criteria include its 60-ball FC-BGA package (4.5 mm × 7 mm), remote-sense differential feedback (FBP/FBN), programmable soft-start slope, integrated over-temperature and over-current protection, and FM+ I²C interface for real-time DVC register writes in safety-critical automotive power domains.
Technical Context
The DA9142-XXF72 implements a synchronous dual-phase buck topology with interleaved 180° phase shift, enabling reduced input/output ripple and improved thermal distribution. Its digital core supervises voltage, current, and temperature using internal ADCs and OTP-configurable thresholds, while the I²C-compatible FM+ interface (up to 1 MHz) allows dynamic adjustment of VOUT and phase shedding modes without external logic.
Each phase integrates 10 mΩ high-side and 8 mΩ low-side MOSFETs, operates with 110 nH inductors and 110 µF total output capacitance, and uses adaptive gate drive timing to maintain efficiency >90% at 10 A load across 2.8 V–5.5 V input. Remote sensing compensates for PCB IR drop, ensuring ±1% regulation at the point-of-load under transient loads up to ±5%.

Pinout & Package
DA9142-XXF72 uses a 60-ball Fine-Pitch Chip Scale Ball Grid Array (FC-BGA) package measuring 4.5 mm × 7 mm with 0.65 mm pitch. The package integrates thermal vias under the die pad for efficient heat transfer to the PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1–PVDD4 | Power supply input for buck phases | Four dedicated high-current power inputs (10 A each) decoupled locally to minimize switching noise coupling. |
| LX1, LX2 | Phase switch node outputs | Interleaved high-side/low-side switching nodes connected to 110 nH inductors; LX3/LX4 are NC. |
| PGND1–PGND4 | Power ground return paths | Four independent power ground balls reduce ground bounce and improve EMI performance in multi-phase layout. |
| FBP / FBN | Differential output voltage sense | Remote sensing pair enables point-of-load regulation; FBP connects to VOUT, FBN ties to local GND at load. |

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 |
|---|---|---|---|
| MPQ4332-AEC1 | Single-phase, 12 A continuous, 2.5 MHz switching, no remote sense, QFN-24 package | Lacks differential feedback and DVC GPIO interface; requires external current sense for over-current protection | Lower cost option where 13 A dual-phase capability and point-of-load accuracy are not required |
| TPS659424-Q1 | Multi-rail PMIC with 4 buck channels (max 6 A each), 2.2 MHz, I²C + SPI, 72-pin VQFN | Higher integration but lower per-rail current capability; no 20 A peak rating or 4 MHz operation | Better fit for multi-rail SoC power trees needing sequencing and monitoring-not optimized for single-rail 13 A+ loads |
Compared with MPQ4332-AEC1 and TPS659424-Q1, DA9142-XXF72 uniquely combines 20 A peak current, 4 MHz operation, and differential remote sensing in a compact FC-BGA-making it the only choice for space-constrained ADAS ECUs demanding both high current density and sub-1% load regulation.

FAQ
What is the maximum junction temperature specification for DA9142-XXF72?
The DA9142-XXF72 has a maximum junction temperature (TJ) rating of 150°C, with programmable thermal warning (TJ_WARN = 125°C) and critical shutdown (TJ_CRIT_WC = 150°C) thresholds. These limits are enforced by on-die temperature sensors and require no external components. The device remains fully operational up to 125°C ambient (TA) under recommended conditions, and DA9142-XXF72's thermal resistance (θJA = 16.4°C/W, no heatsink) ensures reliable derating in enclosed automotive environments.
Does DA9142-XXF72 support dynamic voltage control (DVC) without I²C communication?
Yes, DA9142-XXF72 supports DVC via dedicated GPIO pins (e.g., CONF/GPIO0 or GPIO1) configured as voltage control inputs, enabling analog or digital step-based VOUT adjustment independent of I²C. This mode uses internal resistor ladders and comparators to map input logic levels or analog voltages to predefined output voltage codes. DA9142-XXF72 retains full DVC functionality even if the I²C bus is disabled, making it suitable for safety-critical systems where serial interface failure must not compromise voltage adaptability.
What is the purpose of the FBP and FBN pins on DA9142-XXF72?
The FBP (feedback positive) and FBN (feedback negative) pins implement differential remote voltage sensing for DA9142-XXF72, allowing regulation accuracy to be maintained directly at the load rather than at the IC's output pads. FBP connects to the VOUT net at the processor's power pin, while FBN connects to the local ground reference near that same pin-canceling PCB trace resistance effects. This configuration ensures DA9142-XXF72 achieves ±1% output accuracy despite up to 50 mV IR drop across board traces, which is essential for modern low-voltage, high-current SoCs.
Can DA9142-XXF72 operate with only one phase enabled?
Yes, DA9142-XXF72 supports single-phase operation via register-controlled phase shedding, automatically disabling Phase 2 under light loads (<2 A) to improve efficiency and reduce quiescent current. This mode is managed internally without host intervention and maintains full regulation, protection, and DVC functionality. DA9142-XXF72's dual-phase architecture is not mandatory-engineers may configure it as a single-phase 13 A converter or allow auto-shedding, depending on thermal and efficiency targets in the final application.
Is DA9142-XXF72 pin-compatible with earlier DA9142 variants like DA9142-A?
Yes, DA9142-XXF72 is a drop-in replacement for DA9142-A, sharing identical 60-ball FC-BGA mechanical footprint, pin assignment, thermal pad layout, and electrical interface behavior. All registers, I²C commands, GPIO functions, and protection thresholds remain unchanged between revisions. DA9142-XXF72 incorporates minor internal process enhancements but maintains full functional, timing, and qualification equivalence-including AEC-Q100 Grade 1 compliance and automotive temperature range support-making it a seamless upgrade path.
