Product details
Overview
DA9142-XXF72-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 nominal switching frequency. It integrates high-side/low-side FETs, supports dynamic voltage control (DVC) via I²C or GPIO, and targets point-of-load regulation in ADAS and infotainment power rails.
For engineers reviewing the DA9142-XXF72-A datasheet, DA9142-XXF72-A pinout, DA9142-XXF72-A application, or DA9142-XXF72-A equivalent, key selection criteria include its dual-phase 20 A peak capability, remote-sense differential feedback (FBP/FBN), FM+ I²C interface, programmable soft-start, and integrated thermal/current protection - all in a 60-ball FC-BGA package optimized for automotive thermal and EMI constraints.
Technical Context
The DA9142-XXF72-A implements a synchronous dual-phase buck topology with interleaved 180° phase timing to reduce input/output ripple and improve transient response. Its digital core manages real-time DVC through register writes or dedicated GPI pins, enabling adaptive voltage scaling for AI engines and GPU cores.
It features fully integrated 10 mΩ high-side and 8 mΩ low-side MOSFETs per phase, remote-sense differential feedback (FBP/FBN) for ±1% load regulation at point-of-load, and autonomous over-temperature shutdown triggered at TJ_WARN (125°C) and TJ_CRIT_WC (150°C) thresholds without external sensors.
Key Specifications

Pinout & Package
DA9142-XXF72-A uses a 60-ball Fine-Pitch Chip-Scale Ball Grid Array (FC-BGA) package measuring 4.5 mm × 7.0 mm with 0.65 mm pitch. The layout separates noisy power grounds (PGND1–PGND4), analog ground (AGND), and quiet supply rails (AVDD, PVDDx) to suppress coupling between switching and control domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1–PVDD4 | Power supply input for buck phases | Four independent high-current inputs (10 A each) decoupled locally to minimize switching noise injection into control circuitry. |
| LX1, LX2 | Switch node outputs | Interleaved phase outputs driving 110 nH inductors; LX3/LX4 are No Connect (NC) - confirmed in datasheet Table 1. |
| PGND1–PGND4 | Power ground return paths | Dedicated low-inductance GND balls per phase to contain high di/dt return currents and reduce EMI. |
| FBP / FBN | Differential feedback sense inputs | Enables remote sensing at point-of-load: FBP connects to VOUT1 rail, FBN connects to local GND near load. |
| SCL/GPIO3, SDA/GPIO4 | I²C bus interface or GPIO | FM+ I²C pins support 1 MHz operation; configurable as general-purpose I/O when I²C disabled. |
| CONF/GPIO0 | Configuration select / GPIO | Hardware pin that sets I²C slave address during power-up; also usable as programmable input after initialization. |
| IC_EN | Control interface enable | Active-high signal enabling bandgap reference, oscillator, and I²C logic - critical for sequencing control. |
| GPIO1–GPIO2 | General-purpose I/O | 10 mA drive strength; configurable as interrupt outputs or status indicators per register settings. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase interleaved buck | Reduces input RMS current by ~30% and output voltage ripple amplitude by >50% vs. single-phase 20 A design. |
| Dynamic Voltage Control (DVC) | Enables real-time VOUT adjustment via I²C write or GPIO edge trigger - essential for DVFS in AI SoCs. |
| Programmable soft-start | Configurable ramp time prevents inrush current damage to input capacitors and upstream power sources. |
| Integrated current & temperature supervision | Eliminates external current-sense amplifiers and thermal sensors - reduces BOM count and layout area. |
| Remote-sense differential feedback | Compensates for up to 50 mΩ PCB trace resistance between converter and load, maintaining ±1% regulation. |
| Configurable I²C address | CONF/GPIO0 pin selects one of four I²C addresses - supports up to four DA9142-XXF72-A devices on same bus. |

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 | Single-phase, 15 A continuous, 24 A peak; no remote sensing; requires external current sense resistor. | Lacks differential feedback and DVC - suitable for fixed-voltage loads only, not DVFS-critical AI/SoC rails. | Select when cost sensitivity outweighs need for adaptive voltage control and point-of-load accuracy. |
| TPS659424RHBR | Multi-rail PMIC with 12 A buck (non-interleaved); includes LDOs, sequencer, and watchdog - larger 7-mm × 7-mm QFN. | Integrates system power management but offers lower peak current and no dual-phase ripple reduction. | Prefer when board space allows larger package and system-level sequencing/integration is required over pure buck performance. |
Compared with MPQ8633BGLE-Z and TPS659424RHBR, the DA9142-XXF72-A uniquely combines dual-phase 20 A peak delivery, ±1% remote-sense accuracy, and hardware-accelerated DVC in a 4.5 mm × 7 mm FC-BGA - making it optimal for next-gen automotive AI and ADAS point-of-load applications where transient fidelity and thermal density are critical.

FAQ
What is the maximum junction temperature specification for the DA9142-XXF72-A?
The DA9142-XXF72-A has a maximum junction temperature (TJ) of 150°C, with thermal warning (TJ_WARN) set at 125°C and critical shutdown (TJ_CRIT_WC) at 150°C. These thresholds are enforced by integrated thermal monitoring circuitry - no external sensor is required. The device remains fully operational up to 125°C ambient with appropriate heatsinking, and the DA9142-XXF72-A automatically throttles output current above that point to maintain safe silicon temperatures.
Does the DA9142-XXF72-A support dynamic voltage scaling (DVS) or dynamic voltage control (DVC)?
Yes, the DA9142-XXF72-A supports Dynamic Voltage Control (DVC) via two independent methods: register-based I²C writes to the BUCK_BUCK1_x registers, or hardware-triggered adjustment using the CONF/GPIO0 or GPIO1 pins. This enables real-time VOUT changes - for example, stepping from 0.85 V to 0.65 V during CPU idle states. The DA9142-XXF72-A implements DVC with sub-10 µs response time and maintains ±1% accuracy throughout the 0.5 V–1.3 V range.
What is the purpose of the FBP and FBN pins on the DA9142-XXF72-A?
The FBP (feedback positive) and FBN (feedback negative) pins implement differential remote voltage sensing for the DA9142-XXF72-A's output rail. FBP connects directly to the load's VOUT node, while FBN connects to the load's local ground - compensating for IR drop across PCB traces. This configuration ensures ±1% output voltage accuracy at the point-of-load, even with up to 50 mΩ total trace resistance. The DA9142-XXF72-A uses this feedback pair exclusively for closed-loop regulation; no single-ended FB pin is present.
Can the DA9142-XXF72-A operate with only one phase enabled?
No - the DA9142-XXF72-A is a fixed dual-phase converter with both LX1 and LX2 active simultaneously; phase shedding is not supported. Its architecture relies on interleaved operation to achieve 20 A peak current, 4 MHz switching, and low output ripple. While register bits exist for phase configuration, the datasheet specifies that "dual-phase operation is mandatory" and disables single-phase mode in firmware. All electrical characteristics, including inductor sizing (110 nH per phase) and capacitor requirements (110 µF total), assume both phases are active in the DA9142-XXF72-A.
Is the DA9142-XXF72-A pin-compatible with other devices in the DA91xx family?
No - the DA9142-XXF72-A is not pin-compatible with earlier DA91xx variants such as DA9132 or DA9122. Its 60-ball FC-BGA footprint, pin assignments (e.g., dedicated LX1/LX2, NC LX3/LX4), and power ball distribution are unique to the DA9142-A series. Migration requires PCB redesign. The DA9142-XXF72-A shares register map compatibility with DA9142-A variants but differs mechanically and electrically from prior generations - confirmed in Renesas ordering tables and package drawings.
