Product details
Overview
DA9132-XXRT1-AT from Renesas Electronics is a dual-channel automotive-grade PMIC integrating two fully synchronous buck converters, each delivering up to 3 A at 0.3 V–1.9 V output from a 2.8 V–5.5 V input. It features remote sensing, I²C-compatible FM+ interface, dynamic voltage control (DVC), and AEC-Q100 Grade 2 qualification for use in ADAS, infotainment SoC power rails, and SIPP modules.
For engineers reviewing the DA9132-XXRT1-AT datasheet, DA9132-XXRT1-AT pinout, DA9132-XXRT1-AT application, or DA9132-XXRT1-AT equivalent, key selection considerations include ±1% static output accuracy, 4 MHz switching frequency, integrated over-temperature/over-current protection, wettable-flank 24-pin FCQFN package (3.3 mm × 4.8 mm), and programmable soft-start for rail sequencing in automotive ECU designs.
Technical Context
The DA9132-XXRT1-AT implements two independent single-phase buck regulators with integrated high-side and low-side MOSFETs, eliminating external FETs or Schottky diodes. Each channel supports 4 MHz fixed-frequency PWM operation and adaptive DVC via register write or dedicated GPIO.
Its architecture includes remote-sense differential feedback (FB1P/FB1N, FB2P/FB2N), cycle-by-cycle current limiting, thermal shutdown at 150 °C junction temperature, and configurable GPIOs supporting I²C address selection, Power-Good indication, and interrupt signaling via nIRQ.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436-AEC1 | Single-channel 6 A buck; requires two devices for dual-rail; no integrated DVC or remote sensing. | Higher BoM cost and larger footprint; lacks I²C telemetry and coordinated rail sequencing. | Preferred only when higher per-rail current (>3 A) is required and DVC is not needed. |
| TPS659424-Q1 | Multi-rail PMIC with 4 buck channels; larger 48-pin VQFN; higher quiescent current (25 µA vs. 12 µA). | Better suited for complex ECUs needing >2 rails; over-specified for simple dual-core SoC applications. | Choose when additional LDOs, watchdog timers, or multi-phase support are required beyond DA9132-XXRT1-AT scope. |

FAQ
What is the maximum output current supported by each channel of the DA9132-XXRT1-AT?
The DA9132-XXRT1-AT supports up to 3 A continuous output current per channel under recommended operating conditions (TA ≤ +105 °C, proper PCB thermal design). This rating is validated with 220 nH inductors and 20 µF output capacitance per rail, and includes derating above 85 °C ambient per the power dissipation curve in the datasheet.
Does the DA9132-XXRT1-AT support remote voltage sensing, and how is it implemented?
Yes, the DA9132-XXRT1-AT implements true differential remote sensing via dedicated FB1P/FB1N and FB2P/FB2N pins per channel. This allows the IC to regulate voltage directly at the load point, compensating for IR drop across PCB traces and ensuring ±1 % static accuracy regardless of routing length or copper weight - critical for automotive SoC applications.
What package type and dimensions does the DA9132-XXRT1-AT use?
The DA9132-XXRT1-AT uses a 24-pin FCQFN package with wettable flanks, measuring 3.3 mm × 4.8 mm with 0.5 mm pitch. Its exposed thermal pad and side-wettable leads support automated optical inspection and high-yield reflow soldering in automotive manufacturing lines.
Can the DA9132-XXRT1-AT be used in non-automotive applications?
While the DA9132-XXRT1-AT is AEC-Q100 Grade 2 qualified and optimized for automotive environments, its electrical specifications - including −40 °C to +105 °C operation, 2.8 V–5.5 V input range, and 4 MHz switching - make it technically suitable for industrial or ruggedized computing applications where high reliability and compact power delivery are required.
How is dynamic voltage control (DVC) implemented on the DA9132-XXRT1-AT?
DVC on the DA9132-XXRT1-AT is implemented via either I²C register writes (using the BUCK_BUCKx_0–BUCK_BUCKx_6 registers) or a dedicated GPIO pin configured as DVC input. The feature enables real-time adjustment of output voltage based on processor load state, reducing power consumption during idle or low-activity periods without software intervention.
