Product details
Overview
DA9224-XXFTD-AT from Renesas Electronics is a dual-output, automotive-grade multi-phase buck PMIC designed to supply CPU/GPU and DDR memory rails in ADAS and infotainment systems. It integrates two independent dual-phase buck converters delivering 2 × 8 A output current, supports 0.3–1.57 V programmable output (extendable to 4.3 V via resistor divider), operates from 2.8–5.5 V input, and features remote sensing, dynamic voltage control (DVC), and AEC-Q100 Grade 2 qualification.
For engineers reviewing the DA9224-XXFTD-AT datasheet, DA9224-XXFTD-AT pinout, DA9224-XXFTD-AT application, or DA9224-XXFTD-AT equivalent, key selection criteria include its 2×8 A dual-buck architecture, 3 MHz switching frequency enabling low-profile inductor use, ±1% static output accuracy, -40°C to +105°C operating range, and I²C/SPI-compatible interface with configurable address via GPI.
Technical Context
The DA9224-XXFTD-AT implements two fully independent dual-phase synchronous buck regulators (Buck A and Buck B), each supporting programmable output voltage (0.3–1.57 V) and current limit (4–7 A per phase). Its 3 MHz fixed-frequency PWM operation enables compact magnetics, while automatic phase shedding optimizes light-load efficiency.
It features integrated power switches (29 mΩ PMOS / 21 mΩ NMOS per phase), remote sensing at point-of-load (FBAP/FBAN for Buck A; FBBP/FBBN for Buck B), and dual-mode digital control: I²C-compatible 2-wire or SPI-compatible 4-wire interface with programmable soft start and DVC via register writes or dedicated DVS pin.
Key Specifications

Pinout & Package
DA9224-XXFTD-AT uses a 66-ball TFBGA package with 0.8 mm pitch, optimized for thermal performance and automotive PCB layout. The package includes dedicated high-current LX pins per phase, separate analog/digital ground domains (VSS_A1/A2/B1/B2/VSS_ANA/VSS), and dual-sense inputs for both buck outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1, LX_A2 | Switching node (Buck A) | High-current pulsed nodes connecting to phase inductors; require low-inductance routing |
| LX_B1, LX_B2 | Switching node (Buck B) | Independent high-current nodes for second buck output; isolated from Buck A layout |
| FBAP, FBAN | Remote sense (Buck A) | Differential feedback pair placed at CPU/GPU VDD rail to compensate PCB IR drop |
| FBBP, FBBN | Remote sense (Buck B) | Differential feedback pair for DDR memory rail; NC on DA9223-A variants |
| VDD_A1, VDD_A2, VDD_B1, VDD_B2 | Phase supply inputs | Each tied directly to VSYS; multiple balls per phase reduce voltage drop and thermal stress |
| IC_EN | Enable control | Active-high logic input; 750 µs enable delay ensures controlled startup sequencing |
| nIRQ | Interrupt output | Open-drain signal indicating fault conditions (OCP, OTP, PG loss) to host processor |
| SDA/SCL or SI/SK | I²C/SPI interface | Configurable 2-wire (I²C) or 4-wire (SPI) communication; supports multi-device addressing via GPI |
Key Features
| Feature | Design Value |
|---|---|

| Remote Sensing (Dual) | Separate FBAP/FBAN and FBBP/FBBN pairs eliminate PCB trace resistance error - maintains ±1% regulation at point-of-load |
| Automatic Phase Shedding | Disables unused phases below ~30% load - improves light-load efficiency by up to 15% vs fixed-phase operation |
| Integrated Power Switches | 29 mΩ PMOS + 21 mΩ NMOS per phase - eliminates external FETs, Schottky diodes, and associated layout complexity |
| AEC-Q100 Grade 2 | Qualified for -40°C to +105°C operation with full thermal derating - validated for ADAS camera modules and display clusters |

FAQ
What is the maximum output current capability of the DA9224-XXFTD-AT?
The DA9224-XXFTD-AT integrates two independent dual-phase buck converters, each capable of delivering up to 8 A continuous output current. This gives a total of 2 × 8 A across two regulated rails - for example, 1.0 V for CPU core and 1.2 V for DDR memory - with full thermal derating up to +105°C ambient temperature.
Does the DA9224-XXFTD-AT support remote voltage sensing for both outputs?
Yes, the DA9224-XXFTD-AT supports true differential remote sensing on both outputs: FBAP/FBAN for Buck A and FBBP/FBBN for Buck B. These dedicated sense pins connect directly to the point-of-load (e.g., CPU VDD pin), compensating for PCB trace resistance and ensuring ±1% regulation accuracy regardless of board layout parasitics.
Can the DA9224-XXFTD-AT be configured for I²C or SPI communication?
Yes, the DA9224-XXFTD-AT supports both 2-wire (I²C-compatible) and 4-wire (SPI-compatible) digital interfaces. Pin configuration (e.g., nCS polarity, clock mode) determines protocol behavior, and the same physical pins (SDA/SCL or SI/SK) adapt automatically - enabling flexible integration without hardware redesign.
What is the switching frequency and why does it matter for the DA9224-XXFTD-AT?
The DA9224-XXFTD-AT operates at a nominal 3 MHz switching frequency. This high frequency allows use of ultra-low-profile (1 mm height) inductors and smaller ceramic output capacitors, which is essential for space-constrained automotive modules like camera ECU housings and digital cluster PCBs where vertical clearance is limited to <2.5 mm.
Is the DA9224-XXFTD-AT qualified for automotive applications?
Yes, the DA9224-XXFTD-AT is AEC-Q100 Grade 2 qualified (-40°C to +105°C ambient), with built-in protections including per-phase over-current, over-temperature warning/critical thresholds (110°C/140°C), VDDIO UVLO, and power-good monitoring - meeting functional safety requirements for ASIL-B automotive systems such as ADAS sensors and infotainment head units.
