Product details
Overview
DA9213-XXFSC-AT from Renesas Electronics is an AEC-Q100 Grade 2 qualified, single four-phase synchronous buck PMIC delivering up to 20 A output current for automotive CPU/GPU/DDR rails. It operates from 2.8 V to 5.5 V input, provides 0.3–1.57 V programmable output (extendable to 4.3 V via resistor divider), and features 3 MHz switching frequency, ±1% static voltage accuracy, and remote sensing at point of load - deployed in ADAS domain controllers and infotainment SoC power delivery.
For engineers reviewing the DA9213-XXFSC-AT datasheet, DA9213-XXFSC-AT pinout, DA9213-XXFSC-AT application, or DA9213-XXFSC-AT equivalent, key selection criteria include its 20 A four-phase architecture, I²C/SPI-compatible interface with configurable address, dynamic voltage control (DVC) support, integrated over-temperature/over-current protection, and 66-pin VFBGA 0.5 mm pitch package for high-density automotive PCBs.
Technical Context
The DA9213-XXFSC-AT implements a monolithic four-phase interleaved buck converter with fully integrated high-side and low-side MOSFETs (RON_PMOS = 27 mΩ, RON_NMOS = 19 mΩ per phase), enabling fast transient response (10 A/µs) and automatic phase shedding across full load range. Its digital core supports register-based DVC via I²C or SPI, with programmable soft-start and configurable current limits (4–7 A per phase).
Remote sensing is implemented via dedicated FBAP/FBAN pins for Buck A, ensuring <±20 mV load regulation error under dynamic conditions. The device uses a 3 MHz fixed-frequency PWM mode by default but supports PFM for ultra-low quiescent current (72 µA in full-buck PFM mode), optimized for automotive cold-crank and standby requirements.
Key Specifications

Pinout & Package
DA9213-XXFSC-AT is housed in a 66-pin Very Thin Fine-Pitch Ball Grid Array (VFBGA) package with 0.5 mm pitch, designed for high thermal performance and automotive board-level reliability. Pin assignments are defined per Renesas R16DS0618EJ0231 Rev.02.31.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1–LX_A4 | Switching node (Buck A phases 1–4) | Four dedicated high-frequency switching outputs - each drives one phase's external inductor; requires low-inductance layout to minimize EMI and voltage spikes. |
| VDD_A1–VDD_A4 | Power supply for Buck A phases | Four independent VSYS-connected inputs - decoupled locally to reduce phase-to-phase coupling and improve transient response. |
| FBAP / FBAN | Remote sense inputs for Buck A | Differential feedback pair - connects directly to CPU/GPU VDD rail at point-of-load to compensate for PCB IR drop and maintain tight regulation. |
| IC_EN | Enable control input | Active-high logic signal - controls global power-up sequencing; compatible with automotive microcontroller GPIOs and reset supervisors. |
| nIRQ | Interrupt output | Open-drain fault indicator - asserts on over-temperature, over-current, or UVLO events; pulls host processor interrupt line low for real-time fault handling. |
| SDA / SCL / nCS / SO | I²C/SPI interface signals | Configurable 2-wire (I²C) or 4-wire (SPI) communication - supports register read/write for DVC, current limit, and soft-start configuration without additional protocol ICs. |
| VSS_A1–VSS_A4 | Ground returns for Buck A phases | Eight dedicated ground balls - isolated per-phase return paths minimize ground bounce and improve EMI performance in multi-phase operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2965GQ-DC from Monolithic Power Systems | 6-phase, 60 A total; 500 kHz–1.5 MHz programmable frequency; no integrated DVC pin; requires external DAC for voltage scaling. | Targeted at higher-power ADAS cameras and radar MMICs; lacks AEC-Q100 Grade 2 qualification and remote sensing pins. | Choose when >20 A is required and DVC is handled externally; avoid if PoL sensing or automotive qualification is mandatory. |
| TPS65917B1A1RSLR from Texas Instruments | 7-channel PMIC with 3 buck converters (2× 3 A, 1× 6 A); 2.7–5.5 V input; I²C-only interface; no phase shedding or 3 MHz switching. | Designed for entry-level infotainment with lower SoC complexity; integrates LDOs and RTC but lacks 20 A capability. | Choose for cost-sensitive non-ADAS systems where integration of multiple rails outweighs peak current needs; not suitable for Orin-class processors. |
Compared with MP2965GQ-DC and TPS65917B1A1RSLR, the DA9213-XXFSC-AT uniquely combines AEC-Q100 Grade 2 compliance, 20 A four-phase integration, dedicated DVC and remote sensing, and 3 MHz operation - making it the only drop-in solution for next-generation automotive SoC core rails requiring both high density and functional safety.

FAQ
What is the maximum output current capability of the DA9213-XXFSC-AT?
The DA9213-XXFSC-AT delivers up to 20 A total output current using its four-phase architecture, with each phase rated for 5 A continuous operation. This is confirmed in the R16DS0618EJ0231 datasheet Section 3.3 (Table 6), where IO_MAX per phase is specified as 5000 mA. The device sustains this current across its full operating temperature range (−40 °C to +105 °C) with appropriate PCB thermal design and 47 µF output capacitance per phase.
Does the DA9213-XXFSC-AT support dynamic voltage scaling (DVS) for automotive processors?
Yes, the DA9213-XXFSC-AT supports Dynamic Voltage Control (DVC) via either register writes over its I²C/SPI interface or through a dedicated DVS input pin. This feature enables real-time adjustment of the output voltage in response to processor load changes - critical for energy-efficient operation of automotive SoCs like NVIDIA Orin and Qualcomm SA8155P. DVC behavior is detailed in Section 5.1.4 and Table 7 of the R16DS0618EJ0231 datasheet.
What package type and pin count does the DA9213-XXFSC-AT use?
The DA9213-XXFSC-AT uses a 66-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA) package with 0.5 mm pitch, as specified in Section 8.1 of the R16DS0618EJ0231 datasheet and shown in Figure 30. This package supports high-density automotive PCB layouts and provides dedicated ground balls per phase (VSS_A1–VSS_A4) to minimize noise coupling between interleaved phases.
Is the DA9213-XXFSC-AT qualified for automotive applications?
Yes, the DA9213-XXFSC-AT is AEC-Q100 Grade 2 qualified, meaning it is certified for operation from −40 °C to +105 °C ambient temperature and has passed rigorous stress testing for automotive use. This qualification is explicitly stated on page 1 of the R16DS0618EJ0231 datasheet and reinforced in Section 3.2 (Table 5) and Section 5.5 (temperature supervision).
How does remote sensing work on the DA9213-XXFSC-AT?
The DA9213-XXFSC-AT implements remote sensing via the FBAP (positive) and FBAN (negative) pins, which form a differential feedback pair connected directly to the CPU/GPU power rail at the point of load. This compensates for voltage drop across PCB traces, ensuring ±1% regulation accuracy at the load rather than at the IC output. The implementation is described in Section 5.2.2 and Figure 1 of the R16DS0618EJ0231 datasheet.
