Product details

Overview

DA9223-XXFTD-AT from Renesas Electronics is a single four-phase synchronous buck PMIC optimized for CPU/GPU/DDR power delivery in automotive infotainment and ADAS systems. It delivers up to 16 A output current, supports 0.3 V–1.57 V programmable output (extendable to 4.3 V with external resistor divider), operates from 2.8 V–5.5 V input, and features 3 MHz switching frequency with ±1 % static voltage accuracy.

For engineers reviewing the DA9223-XXFTD-AT datasheet, DA9223-XXFTD-AT pinout, DA9223-XXFTD-AT application, or DA9223-XXFTD-AT equivalent, this page provides verified technical context, validated pin functions, automotive-grade thermal and protection specs, and real-world implementation guidance for in-vehicle power rail design.

Technical Context

The DA9223-XXFTD-AT implements a fully integrated four-phase buck converter architecture with internal high-side and low-side MOSFETs (RON_PMOS = 29 mΩ, RON_NMOS = 21 mΩ per phase), remote sensing via FBAP/FBAN pins, and dynamic voltage control (DVC) via I²C/SPI-compatible interface. Its 3 MHz fixed-frequency PWM operation enables use of compact 0.22 µH inductors and supports automatic phase shedding under light load.

It integrates AEC-Q100 Grade 2 qualified safety features including over-temperature warning/critical thresholds (110 °C / 125 °C), over-current limit (programmable 4–7 A per phase), VDDIO under-voltage lockout (1.315–1.55 V), and power-good monitoring with ±50 mV hysteresis - all without external sensing components.

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; 2.7–16 V input; no remote sensing; I²C only (no SPI compatibility)	Lacks DVC pin interface and grade-2 automotive qualification; suitable for industrial but not safety-critical vehicle systems	Select when wider input range (up to 16 V) is required and AEC-Q100 compliance is not mandated.
TPS65917B1RSLR	7-rail PMIC with 3 buck converters (2×3 A + 1×6 A); integrated LDOs; 2.7–5.5 V input; -40°C to +105°C	Lower per-rail current capability; no 16 A single-rail option; includes audio codec and USB PHY - higher integration but less flexibility for high-current cores	Select when system requires mixed-rail support (core, memory, I/O) and space-constrained integration outweighs peak current needs.

Compared with MPQ8633BGLE-Z and TPS65917B1RSLR, DA9223-XXFTD-AT uniquely combines 16 A single-rail capability, automotive-grade thermal/safety certification, and DVC pin control - making it the only direct fit for next-gen automotive SoC core power where transient response, reliability, and footprint efficiency are jointly constrained.

FAQ

What is the maximum output current supported by DA9223-XXFTD-AT?

DA9223-XXFTD-AT supports up to 16 A continuous output current using its integrated four-phase buck architecture. This rating assumes proper thermal management on a 6-layer PCB with ≥2 oz copper, ambient temperature ≤70 °C, and derating per the 29.3 mW/°C curve above 70 °C. Each phase delivers up to 4 A, and current sharing is actively balanced internally.

Does DA9223-XXFTD-AT support remote voltage sensing, and how is it implemented?

Yes, DA9223-XXFTD-AT implements remote sensing via dedicated FBAP and FBAN pins for Buck A. These differential inputs connect directly to the CPU's VDD and VSS pins at the point of load, enabling compensation for PCB trace IR drop. The IC regulates based on this remote feedback, maintaining ±1 % accuracy at the die rather than at the PMIC output.

Can DA9223-XXFTD-AT be used with both I²C and SPI interfaces?

DA9223-XXFTD-AT features a 2/4-wire interface that is electrically and protocol-compatible with standard I²C (2-wire) and SPI (4-wire) buses. Pin mapping supports either mode: SDA/SCL for I²C; SI/SO/SK/nCS for SPI. Configuration is handled via hardware strapping (GPI pins) and register settings - no external level shifters required.

What protection features are integrated into DA9223-XXFTD-AT?

DA9223-XXFTD-AT integrates over-current protection (per-phase, programmable 4–7 A), over-temperature warning (110 °C) and critical shutdown (125 °C), VDDIO under-voltage lockout (1.315–1.55 V), VDD UVLO (2.55 V), and power-good monitoring with ±50 mV hysteresis. All protections trigger internal fault latching and assert nIRQ without external components.

Is DA9223-XXFTD-AT qualified for automotive applications, and what is its temperature rating?

Yes, DA9223-XXFTD-AT is AEC-Q100 Grade 2 qualified, rated for −40 °C to +105 °C ambient operation. Its junction temperature is specified up to +125 °C, and thermal derating begins at 70 °C ambient (29.3 mW/°C). The device undergoes full automotive reliability stress testing including HTOL, TC, and UHAST per AEC-Q100 Rev G.
