Product details
Overview
DA9213-XXFS1-A from Renesas Electronics is an AEC-Q100 Grade 2 qualified, single four-phase synchronous buck PMIC delivering up to 20 A output current for CPU/GPU/DDR rails in automotive infotainment and ADAS systems. It operates from 2.8 V to 5.5 V input, provides 0.3–1.57 V programmable output (extendable to 4.3 V via resistor divider), and features 3 MHz switching frequency, ±1% static voltage accuracy, and remote sensing at point of load.
For engineers reviewing the DA9213-XXFS1-A datasheet, DA9213-XXFS1-A pinout, DA9213-XXFS1-A application, or DA9213-XXFS1-A equivalent, key selection considerations include its 20 A four-phase architecture, I²C/SPI-compatible interface with configurable address, dynamic voltage control (DVC), integrated power switches, and -40 °C to +105 °C operating range for automotive-grade reliability.
Technical Context
The DA9213-XXFS1-A implements a fully integrated four-phase interleaved synchronous buck converter with automatic phase shedding and PWM/PSM mode transition. Its digital core supports register-based DVC via I²C or SPI, enabling real-time voltage scaling synchronized to processor load states.
All four phases are allocated exclusively to Buck A, with dedicated LX_A1–LX_A4 switching nodes, VDD_A1/VDD_A2 supply rails, and FBAP/FBAN remote sense inputs - no Buck B functionality is present, distinguishing it from DA9214-A and DA9215-A variants.

FAQ
What is the maximum output current capability of the DA9213-XXFS1-A?
The DA9213-XXFS1-A delivers up to 20 A total output current using its four-phase architecture, with each phase rated for 5 A continuous operation. This is achieved without external power FETs, as all high-side and low-side MOSFETs are fully integrated within the IC. The device maintains this rating across its full -40 °C to +105 °C operating temperature range and supports programmable current limiting between 4 A and 7 A per phase.
Does the DA9213-XXFS1-A support dynamic voltage scaling (DVS) via hardware pin or only through software registers?
The DA9213-XXFS1-A supports Dynamic Voltage Control (DVC) through both methods: a dedicated DVS input pin enables direct hardware-based voltage adjustment using an external DAC or GPIO-controlled resistor ladder, while the same function is also accessible via I²C or SPI register writes. This dual-path capability allows system designers to implement either fast analog-triggered scaling or precise firmware-managed DVFS sequences - both fully supported in the DA9213-XXFS1-A's silicon implementation.
What package type and pin count does the DA9213-XXFS1-A use?
The DA9213-XXFS1-A uses a 66-ball Very Fine Pitch Ball Grid Array (VFBGA) package with 0.5 mm pitch and 4.0 mm × 4.0 mm body size. This package is optimized for automotive thermal performance and high-density routing, featuring dedicated ground balls per phase group (VSS_A1/VSS_A2) and separate power supply balls for each phase (VDD_A1/VDD_A2). Pin assignments are documented in Table 2 of the R16DS0618EJ0231 datasheet.
Can the DA9213-XXFS1-A be used with remote sensing for improved load regulation accuracy?
Yes, the DA9213-XXFS1-A includes dedicated differential remote sense inputs FBAP and FBAN for Buck A, enabling precise point-of-load (PoL) voltage regulation. These pins compensate for IR drop across PCB traces up to 100 mV, maintaining ±1% static accuracy even with 50 mΩ trace resistance. Remote sensing is enabled by default and requires no configuration - simply route FBAP/FBAN directly to the load-side terminals of the output capacitor bank.
Is the DA9213-XXFS1-A qualified for automotive applications, and what is its AEC-Q100 grade?
Yes, the DA9213-XXFS1-A is fully AEC-Q100 qualified to Grade 2, specifying operation from -40 °C to +105 °C ambient temperature with robust ESD (2 kV HBM) and latch-up immunity. It includes integrated over-temperature protection with programmable thresholds, VDDIO under-voltage lockout, and cycle-by-cycle over-current detection - all validated per automotive stress test requirements. This qualification makes it suitable for front-end infotainment, digital clusters, and ADAS ECUs deployed in passenger vehicles.
