Product details
Overview
DA9223-XXFT1-AT from Renesas Electronics is a single four-phase automotive-grade buck converter PMIC delivering up to 16 A output current, optimized for CPU/GPU/DDR rails in ADAS and infotainment systems. It operates from 2.8 V–5.5 V input, delivers 0.3 V–1.57 V (or up to 4.3 V with resistor divider) output voltage, features 3 MHz switching frequency, ±1% static accuracy, and -40 °C to +105 °C operation.
For engineers reviewing the DA9223-XXFT1-AT datasheet, DA9223-XXFT1-AT pinout, DA9223-XXFT1-AT application, or DA9223-XXFT1-AT equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification, integrated power switches, remote sensing capability, I²C/SPI-compatible interface, and dynamic voltage control support for adaptive processor supply scaling.
Technical Context
The DA9223-XXFT1-AT implements a fully integrated 4-phase synchronous buck architecture with programmable soft-start, automatic phase shedding, and Dynamic Voltage Control (DVC) via register writes or dedicated DVS pin. Its 3 MHz nominal switching frequency enables use of low-profile 0.22 µH inductors while maintaining fast transient response (10 A/µs).
It supports dual-sensing topology with FBAP/FBAN pins for Buck A and includes dedicated LX nodes per phase (LX_A1/LX_A2), VDD/VSS power domains per phase group, and configurable I²C address selection via GPI inputs-enabling multi-PMIC coordination on shared buses without external address hardware.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1 / LX_A2 | Switching node (Phase 1 & 2) | High-current, high-dV/dt outputs driving external inductors; require tight layout and Kelvin sensing paths. |
| FBAP / FBAN | Remote sense inputs (Buck A) | Enable point-of-load voltage regulation by measuring at CPU die pads, compensating for PCB IR drop. |

| SCL / SDA | I²C interface pins | Support standard/fast/fast-plus modes; tolerate 0.3×VDDIO to 0.7×VDDIO thresholds for robust communication in noisy environments. |
| GPI0 / GPI1 | General-purpose inputs | Configurable for DVC tracking or clock input; GPI0 supports TRK mode for real-time voltage adjustment synchronized to processor activity. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| MPQ8633BGLE-Z | 3-phase, 15 A max; no integrated DVC pin; requires external resistor network for voltage scaling. | Lacks native DVS pin and TRK-mode GPI; relies on I²C-only DVC, increasing software overhead. | Choose when DVC timing constraints are relaxed and cost sensitivity outweighs real-time analog control needs. |
| TPS65917B1A1RSLR | 7-channel PMIC with 2x 6 A bucks; lower max current per rail; fixed 2.2 MHz fSW; no remote sensing on main CPU rail. | Designed for TI Sitara AMxxxx SoCs; lacks dedicated FBAP/FBAN for CPU core; limited to 6 A per buck. | Prefer for TI ecosystem designs where integrated RTC, LDOs, and sequencer reduce BoM count despite lower current capability. |
Compared with MPQ8633BGLE-Z and TPS65917B1A1RSLR, DA9223-XXFT1-AT uniquely combines 16 A four-phase delivery, dedicated DVS/TRK pins for hardware-accelerated voltage scaling, and true remote sensing on the primary CPU rail-making it optimal for high-performance automotive processors requiring deterministic power response.

FAQ
What is the maximum output current supported by DA9223-XXFT1-AT?
DA9223-XXFT1-AT supports up to 16 A continuous output current using its integrated four-phase synchronous buck architecture. Each phase delivers up to 4 A, with current sharing balanced across phases. The device maintains this rating across its full operating temperature range (-40 °C to +105 °C) when used with appropriate PCB copper area and thermal vias per Renesas' evaluation board layout guidelines. DA9223-XXFT1-AT achieves this without external FETs due to its fully integrated 29 mΩ PMOS and 21 mΩ NMOS power stages.
Does DA9223-XXFT1-AT support remote voltage sensing, and how is it implemented?
Yes, DA9223-XXFT1-AT supports true remote sensing via dedicated FBAP and FBAN pins for Buck A. These differential inputs measure voltage directly at the load (e.g., CPU VDD balls), enabling compensation for PCB trace resistance and ensuring ±1% regulation accuracy at the point of load-not just at the IC's output pad. This feature is essential for high-current, low-voltage rails where even 50 mΩ of trace resistance causes significant IR drop. DA9223-XXFT1-AT does not support remote sensing for Buck B, as that function is reserved for the DA9224-A variant.
How does Dynamic Voltage Control (DVC) operate on DA9223-XXFT1-AT?
DA9223-XXFT1-AT supports DVC through two independent paths: (1) register-based control via its I²C/SPI-compatible interface, allowing software-defined voltage updates; and (2) hardware-triggered control using the dedicated DVS input pin and GPI0 in TRK mode, enabling cycle-accurate voltage scaling synchronized to processor workload. This dual-path architecture lets DA9223-XXFT1-AT respond to load changes in under 1 µs-critical for minimizing dynamic power in automotive SoCs. The DVC range spans the full 0.3 V–1.57 V output window in 10 mV steps.
What package type and pin count does DA9223-XXFT1-AT use?
DA9223-XXFT1-AT uses a 66-ball Thin Fine-Pitch Ball Grid Array (TFBGA) package with 0.8 mm ball pitch. The package measures 6.0 mm × 6.0 mm and features segregated power (VDD_A1/VDD_A2/VSS_A1/VSS_A2), analog (FBAP/FBAN), and digital (SCL/SDA/nIRQ) ball groups to minimize noise coupling. Pin mapping follows Renesas' standardized 66-ball layout shown in Figure 3 of the datasheet, with LX_A1/LX_A2 nodes occupying rows B and E for optimal high-current routing. DA9223-XXFT1-AT shares this exact package with DA9224-A but disables FBBP/FBBN pins (marked NC).
Is DA9223-XXFT1-AT qualified for automotive applications, and what standards does it meet?
Yes, DA9223-XXFT1-AT is AEC-Q100 Grade 2 qualified, certified for operation from -40 °C to +105 °C ambient temperature. It includes integrated over-temperature protection with warning (125 °C), critical shutdown (140 °C), and power-on reset (150 °C) thresholds, plus over-current protection per phase and VDDIO under-voltage lockout. The device also meets JEDEC JESD22-A114 reliability standards and supports automotive PPAP documentation packages. DA9223-XXFT1-AT is specifically designed for ASIL-B capable systems when used with appropriate system-level diagnostics.
