Product details
Overview
DA9132-XXRT2-A from Renesas Electronics is a dual-channel, automotive-grade power management IC (PMIC) integrating two fully synchronous buck converters for CPU/GPU and DDR memory rail regulation. It delivers up to 3 A per channel across 0.3 V–1.9 V output, operates from 2.8 V–5.5 V input, features 4 MHz switching, remote sensing, and I²C-compatible FM+ interface. Used in ADAS, infotainment, and SIPP modules.
For engineers reviewing the DA9132-XXRT2-A datasheet, DA9132-XXRT2-A pinout, DA9132-XXRT2-A application, or DA9132-XXRT2-A equivalent, key selection criteria include AEC-Q100 Grade 2 qualification, ±1% static output voltage accuracy, integrated over-temperature/over-current protection, and dynamic voltage control (DVC) support via register or GPIO.
Technical Context
The DA9132-XXRT2-A implements two independent single-phase buck regulators with integrated high-side and low-side MOSFETs, eliminating external FETs or Schottky diodes. Each channel supports programmable soft-start, cycle-by-cycle current limiting, and remote differential feedback (FB1P/FB1N, FB2P/FB2N) for ±1% output accuracy under load and line variation.
Control is delivered via an I²C-compatible FM+ interface (up to 1 MHz), with configurable GPIOs (GPIO0–GPIO4) supporting DVC, Power-Good indication, interrupt signaling (nIRQ), and multi-device I²C address selection. Thermal protection triggers at 150°C junction temperature and includes automatic recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 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 | 0.3 V to 1.9 V per channel - covers core logic (e.g., 0.8 V CPU), GPU (1.1 V), and DDR I/O (1.8 V) rails. |
| Max Output Current | 3 A per channel - sufficient for high-performance SoC cores and DDR memory subsystems in telematics ECUs. |
| Switching Frequency | 4 MHz nominal - enables use of ultra-small 220 nH inductors and reduces output capacitor count (2 × 10 µF per channel). |
| Output Accuracy | ±1 % static, ±5 % dynamic - ensures stable voltage under load transients typical in processor DVFS transitions. |
| Operating Temp | −40 °C to +105 °C ambient - meets AEC-Q100 Grade 2 requirements for under-hood and center-console automotive environments. |
| Protection Features | Integrated over-temperature, over-current, and thermal shutdown - no external sensing components required. |

FAQ
What is the package type and pin count of the DA9132-XXRT2-A?
The DA9132-XXRT2-A uses a 24-pin FCQFN package with wettable flanks, measuring 3.3 mm × 4.8 mm and featuring 0.5 mm pitch. This package supports automated optical inspection and meets IPC/JEDEC standards for automotive reflow profiles. The pinout includes dual LX nodes, four PGND pins, and differential feedback inputs - all confirmed in Renesas' R16DS0579EJ0300 datasheet Figure 4 and Table 1.
Does the DA9132-XXRT2-A support dynamic voltage scaling (DVS) for processor cores?
Yes, the DA9132-XXRT2-A supports dynamic voltage control (DVC) for adaptive output adjustment based on processor load. DVC can be triggered either by writing to internal registers via its I²C-compatible FM+ interface or by asserting a dedicated GPIO pin. This enables real-time voltage scaling for CPU/GPU cores - reducing power consumption during idle states while maintaining regulation accuracy via remote sensing.
What level of automotive qualification does the DA9132-XXRT2-A hold?
The DA9132-XXRT2-A is AEC-Q100 Grade 2 qualified, certified for operation from −40 °C to +105 °C ambient temperature. This qualification covers stress testing for thermal cycling, humidity, ESD, and lifetime reliability - validating its suitability for non-under-hood but thermally demanding automotive applications including infotainment head units, digital clusters, and telematics control units.
Can the DA9132-XXRT2-A operate without external MOSFETs or diodes?
Yes, the DA9132-XXRT2-A integrates fully synchronous high-side and low-side power MOSFETs for both buck channels. No external FETs, Schottky diodes, or bootstrap components are required. This integration reduces bill-of-materials count, simplifies layout, and improves thermal performance - as explicitly stated in the datasheet's "Benefits" section and System Diagram (Figure 1).
What is the minimum output capacitance required per channel for stable operation of the DA9132-XXRT2-A?
The DA9132-XXRT2-A requires 2 × 10 µF ceramic output capacitors per channel (20 µF total) for stable operation at 4 MHz switching frequency. This value is specified in the "Key Features" section and validated in Application Information (Section 6.1) of the datasheet. Using lower capacitance may compromise transient response and loop stability, especially under 3 A load steps.
