Renesas DA9213-XXFSC-A

Overview

DA9213-XXFSC-A from Renesas Electronics is an AEC-Q100 Grade 2 automotive PMIC configured as a single four-phase synchronous buck converter delivering up to 20 A output current, with 0.3 V–1.57 V programmable output voltage (extendable to 4.3 V via external resistor divider), 3 MHz switching frequency, and ±1% static output voltage accuracy. It serves as the primary CPU/GPU core rail supply in ADAS and infotainment systems requiring fast transient response (10 A/µs) and remote sensing at point of load.

For engineers reviewing the DA9213-XXFSC-A datasheet, DA9213-XXFSC-A pinout, DA9213-XXFSC-A application, or DA9213-XXFSC-A equivalent, key selection criteria include its 20 A four-phase architecture, integrated power switches eliminating external FETs, I²C/SPI-compatible interface with configurable address, dynamic voltage control (DVC), and -40 °C to +105 °C operating range for automotive under-hood environments.

Technical Context

The DA9213-XXFSC-A implements a fully integrated four-phase interleaved synchronous buck topology with internal high-side and low-side MOSFETs (RON_PMOS = 27 mΩ, RON_NMOS = 19 mΩ per phase), supporting automatic phase shedding and PWM/PSM mode transitions. Its digital core includes OTP memory, register-mapped DVC control, and dual-interface support (2-wire I²C and 4-wire SPI) with GPI-configurable I²C addressing.

Remote sensing is implemented via dedicated FBAP/FBAN pins for Buck A only, enabling precise regulation despite PCB IR drop. The device uses a fixed 3 MHz switching frequency to minimize inductor size (supports 0.22 µH, 1 mm height) and integrates over-temperature, over-current, and VDDIO UVLO protection without external components.

FAQ

What is the maximum output current capability of the DA9213-XXFSC-A?

The DA9213-XXFSC-A delivers up to 20 A total output current using its four-phase interleaved buck architecture, with each phase rated for 5 A continuous operation. This is confirmed in the datasheet Section 1 (page 1) and Table 6 (page 12), where IO_MAX per phase is specified as 5000 mA and the device is explicitly described as "a single four-phase buck converter delivering up to 20 A output current." The 20 A rating assumes proper thermal management and recommended external components (e.g., 4×47 µF output capacitors, 0.22 µH inductors).

Does the DA9213-XXFSC-A support remote voltage sensing, and how is it implemented?

Yes, the DA9213-XXFSC-A supports remote sensing exclusively for Buck A via dedicated FBAP and FBAN pins, as documented in Section 2.2 (page 9) and Figure 1 (page 2). These differential analog inputs connect directly to the load's power and ground points, enabling the IC to compensate for PCB trace resistance and maintain ±1% output voltage accuracy at the point of load-even under full 20 A current. Remote sensing is not available for Buck B, which is absent in the DA9213-XXFSC-A configuration.

What communication interfaces does the DA9213-XXFSC-A support, and are they pin-compatible across the DA92xx family?

The DA9213-XXFSC-A supports both 2-wire I²C and 4-wire SPI interfaces using shared pins (SDA/SI, SCL/SK, nCS, SO), as detailed in Sections 5.4.1–5.4.2 (pages 31–35). Pin assignments and electrical characteristics (Table 9 and Table 10) are identical across DA9213-A, DA9214-A, and DA9215-A, ensuring hardware compatibility. However, register maps differ slightly due to distinct phase allocations-requiring firmware adaptation when migrating between variants.

Is the DA9213-XXFSC-A qualified for automotive applications, and what is its temperature rating?

Yes, the DA9213-XXFSC-A is AEC-Q100 Grade 2 qualified, certified for operation from -40 °C to +105 °C ambient temperature, as stated on page 1 and confirmed in Table 5 (page 11). This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD (2 kV HBM), making it suitable for automotive cabin, display cluster, and ADAS ECU applications-but not under-hood engine bay locations requiring Grade 0 or 1.

Can the DA9213-XXFSC-A generate output voltages above 1.57 V, and how is this achieved?

Yes, the DA9213-XXFSC-A can generate output voltages from 1.57 V up to 4.3 V using an external resistor divider connected between VOUT and FBAN, as described in Section 5.1.6 (page 27) and Figure 17 (page 27). The internal DAC reference remains fixed; the divider scales the feedback voltage to maintain regulation. This method is required for powering DDR memory rails or I/O supplies, whereas the 0.3 V–1.57 V range is set digitally via register programming without external components.
