Product details
Overview
DA9214-XXFS1-A from Renesas Electronics is an automotive-grade dual-output, dual-phase per rail PMIC delivering 2 × 10 A output current for CPU/GPU and DDR memory rails in ADAS and infotainment systems. It operates from 2.8 V to 5.5 V input, supports 0.3–1.57 V programmable output (extendable to 4.3 V via resistor divider), and features 3 MHz switching frequency with ±1% static voltage accuracy.
For engineers reviewing the DA9214-XXFS1-A datasheet, DA9214-XXFS1-A pinout, DA9214-XXFS1-A application, or DA9214-XXFS1-A equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification, remote sensing capability at point of load, I²C/SPI-compatible interface with configurable address, dynamic voltage control (DVC), and integrated over-temperature/over-current protection without external sensing components.
Technical Context
The DA9214-XXFS1-A integrates two independent dual-phase buck converters (Buck A and Buck B), each operating in synchronous rectification mode with fully integrated power switches (27 mΩ PMOS / 19 mΩ NMOS per phase). Its 3 MHz nominal switching frequency enables use of low-profile 0.22 µH inductors and supports fast transient response up to 10 A/µs.
It implements automatic phase shedding across both rails, programmable soft-start (50–500 µs), and Dynamic Voltage Control (DVC) via register writes or dedicated DVS pin. Remote sensing is implemented on both FBAP/FBAN (Buck A) and FBBP/FBBN (Buck B), ensuring precise regulation under PCB trace impedance variations.

Pinout & Package
DA9214-XXFS1-A uses a 66-pin Very Fine Pitch Ball Grid Array (VFBGA) package with 0.5 mm pitch, optimized for high-density automotive PCB layouts and thermal performance in constrained spaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1, LX_A2 LX_B1, LX_B2 | Switching node (x4) | High-frequency power switch outputs for Buck A (phases 1&2) and Buck B (phases 1&2); require low-inductance layout to minimize EMI and voltage overshoot. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436-AEC1 | Single 12 A buck; no dual-rail integration; requires two devices for equivalent functionality. | Lacks integrated DVC, remote sensing, and multi-phase phase-shedding logic. | Choose when discrete rail control and lower channel count are preferred over integrated dual-rail coordination. |
| TPS659422-Q1 | 6-rail PMIC with 2× 10 A bucks, but larger 120-ball VQFN package and higher quiescent current (120 µA vs 106 µA in PFM). | Includes additional LDOs and sequencer; over-specified if only dual high-current bucks are needed. | Choose when system requires mixed-rail support (LDOs, always-on rails) alongside dual 10 A bucks. |
Compared with MPQ4436-AEC1 and TPS659422-Q1, the DA9214-XXFS1-A provides tightly coupled dual-buck control with minimal footprint (66 VFBGA), lowest PFM quiescent current among alternatives, and native automotive safety features including VDDIO UVLO and OTP reporting via nIRQ-making it optimal for space-constrained ADAS and IVI modules requiring coordinated rail management.

FAQ
What is the maximum output current per rail supported by the DA9214-XXFS1-A?
The DA9214-XXFS1-A supports up to 10 A per rail-Buck A delivers 10 A across two phases, and Buck B independently delivers 10 A across its two phases. Each phase is rated for 5 A continuous, and the device implements automatic phase shedding to maintain efficiency across load ranges from 2 mA to full 10 A per rail.
Does the DA9214-XXFS1-A support remote sensing for both output rails?
Yes, the DA9214-XXFS1-A supports true differential remote sensing on both rails: FBAP/FBAN for Buck A and FBBP/FBBN for Buck B. This allows precise voltage regulation at the point of load, compensating for PCB trace resistance and ensuring ±1% accuracy even with 50 mΩ total path impedance between IC and load.
Can the DA9214-XXFS1-A operate with input voltages below 3.0 V?
Yes, the DA9214-XXFS1-A operates from 2.8 V to 5.5 V input, making it compatible with brown-out conditions during automotive cold-crank (down to ~2.8 V) and single-cell Li-ion battery systems. The device maintains regulation and protection functions across this full range, including OCP and OTP monitoring.
How is Dynamic Voltage Control (DVC) implemented on the DA9214-XXFS1-A?
DVC on the DA9214-XXFS1-A can be activated either through register writes via the I²C/SPI-compatible interface or by applying a voltage to the dedicated DVS pin. This adjusts the output voltage of Buck A or Buck B in real time-enabling adaptive power scaling for CPU/GPU DVFS without host processor intervention.
Is the DA9214-XXFS1-A pin-compatible with other devices in the DA92xx family?
No, the DA9214-XXFS1-A is not pin-compatible with DA9213-A or DA9215-A. While all three share the same 66-pin VFBGA package and pinout layout, their internal buck allocations differ: DA9214-A assigns phases B1/B2 exclusively to Buck B, whereas DA9215-A reassigns B2 to Buck A. This functional difference makes direct substitution unsafe without schematic and firmware validation.
