Product details
Overview
DA9223-XXFTD-A from Renesas Electronics is a single four-phase synchronous buck converter PMIC optimized for CPU/GPU and DDR memory rails in automotive ADAS, infotainment, and telematics systems. It delivers up to 16 A output current, operates from 2.8 V to 5.5 V input, supports 0.3 V–1.57 V programmable output (extendable to 4.3 V with resistor divider), and features 3 MHz switching frequency with ±1 % static voltage accuracy.
For engineers reviewing the DA9223-XXFTD-A datasheet, DA9223-XXFTD-A pinout, DA9223-XXFTD-A application, or DA9223-XXFTD-A equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification, remote sensing capability, I²C/SPI-compatible interface, dynamic voltage control (DVC), and integrated over-temperature/over-current protection for high-reliability automotive power delivery.
Technical Context
The DA9223-XXFTD-A implements a fully integrated 4-phase interleaved buck architecture with internal high-side and low-side MOSFETs (RON_PMOS = 29 mΩ, RON_NMOS = 21 mΩ per phase), enabling fast transient response of 10 A/µs and automatic phase shedding to optimize light-load efficiency. Its 3 MHz nominal switching frequency allows use of compact 0.22 µH inductors and supports tight regulation across load steps.
It employs dual-point remote sensing (FBAP/FBAN) for Buck A and integrates a configurable 2-/4-wire digital interface (I²C/SPI-compatible) with programmable I²C address via GPI pins. The device includes dedicated DVC control logic, adjustable soft-start, and comprehensive supervision including VDDIO UVLO (1.315–1.55 V), thermal warning (110–140 °C), and critical shutdown (125–155 °C).

FAQ
What is the maximum output current capability of the DA9223-XXFTD-A?
The DA9223-XXFTD-A delivers up to 16 A total output current using its integrated four-phase buck architecture, with each phase rated for 4 A continuous operation. This is confirmed in the datasheet's General Description and Electrical Characteristics (Table 5, IO_MAX = 4000 mA per phase). The device sustains this current across its full −40 °C to +105 °C operating ambient range with appropriate thermal management on a 6-layer PCB.
Does the DA9223-XXFTD-A support remote voltage sensing, and how is it implemented?
Yes, the DA9223-XXFTD-A implements remote sensing for Buck A using dedicated FBAP (positive) and FBAN (negative) pins, as specified in Table 1 and Figure 1 of the datasheet. This dual-point sensing compensates for PCB trace resistance between the IC and point-of-load, ensuring ±1 % static output accuracy is maintained at the load rather than at the IC output pin.
Can the DA9223-XXFTD-A be used in dual-buck configurations like the DA9224-A?
No, the DA9223-XXFTD-A is a single four-phase buck converter and does not support dual-buck operation. Pins FBBP and FBBN (B8–B11, E8–E11 switching nodes and D6/E6 sense inputs) are marked "NC" (no connect) for DA9223-XXFTD-A in Table 1 and Figure 3. Only the DA9224-A variant integrates two independent dual-phase bucks.
What digital interfaces does the DA9223-XXFTD-A support, and are they pin-compatible?
The DA9223-XXFTD-A supports both 2-wire (I²C-compatible) and 4-wire (SPI-compatible) digital interfaces using shared pins (A5/A6 for SDA/SCL; D5/C7 for nCS/SO). Interface mode is determined by strap configuration and firmware initialization-not hardware pin remapping-so no physical pin changes are needed to switch protocols.
Is the DA9223-XXFTD-A qualified for automotive applications, and what standards does it meet?
Yes, the DA9223-XXFTD-A is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C ambient), as explicitly stated in the Key Features section and Table 4 of the datasheet. It also includes automotive-grade safety features: VDDIO under-voltage lockout, over-temperature warning/critical thresholds (110–140 °C / 125–155 °C), and over-current protection-all implemented without external components.
