Product details
Overview
DA9214-XXFSC-A from Renesas Electronics is an automotive-grade dual-output PMIC integrating two independent dual-phase synchronous buck converters, delivering 2 × 10 A output current per rail. It supports programmable output voltage from 0.3 V to 1.57 V (±1% static accuracy), operates from 2.8 V–5.5 V input, and features remote sensing, Dynamic Voltage Control (DVC), and I²C/SPI-compatible interface - optimized for CPU/GPU/DDR power delivery in ADAS and infotainment systems.
For engineers reviewing the DA9214-XXFSC-A datasheet, DA9214-XXFSC-A pinout, DA9214-XXFSC-A application, or DA9214-XXFSC-A equivalent, key selection criteria include its dual 10 A capability, 3 MHz switching frequency enabling low-profile inductor use, AEC-Q100 Grade 2 qualification, -40 °C to +105 °C operation, and integrated over-temperature/over-current protection without external sensing components.
Technical Context
The DA9214-XXFSC-A implements two fully independent dual-phase buck regulators (Buck A and Buck B), each with dedicated phase allocation (A1/A2 and B1/B2), programmable current limits (4–7 A per phase), and automatic phase shedding. Its 3 MHz fixed-frequency PWM architecture ensures fast transient response (10 A/µs) and tight load regulation (±3.5% under 5 A step).
It integrates all power switches (PMOS/NMOS with 27 mΩ/19 mΩ RON), supports both local and remote voltage sensing via FBAP/FBAN and FBBP/FBBN, and provides DVC via register writes or dedicated DVS pin - enabling adaptive supply scaling for multi-core processors in automotive environments.

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 (Monolithic Power) | Single 12 A buck (not dual-rail); requires two ICs for equivalent functionality; lower switching frequency (1.2 MHz) | Lacks native dual independent rails and DVC pin - needs external logic for coordinated voltage scaling | Consider only when space allows dual IC placement and system-level DVC implementation is feasible |
| TPS659424-Q1 (Texas Instruments) | Multi-rail PMIC with 4 buck channels (including dual 10 A), but larger 120-pin VQFN; higher quiescent current in PFM | Includes integrated LDOs and sequencer - over-specified if only dual high-current buck rails are needed | Prefer when additional power rails or complex power sequencing is required beyond DA9214-XXFSC-A's scope |
Compared with MPQ4436-AEC1 and TPS659424-Q1, the DA9214-XXFSC-A delivers optimal integration for dual 10 A applications - combining compact 66-ball VFBGA packaging, native DVC support, and automotive-qualified dual-buck architecture without requiring auxiliary ICs or layout overhead.

FAQ
What is the maximum output current per rail supported by the DA9214-XXFSC-A?
The DA9214-XXFSC-A supports up to 10 A per rail, delivered by two independent dual-phase buck converters (Buck A and Buck B). Each rail uses two phases with integrated 27 mΩ PMOS and 19 mΩ NMOS switches, enabling efficient high-current delivery with minimal thermal derating at +105 °C ambient. The DA9214-XXFSC-A datasheet confirms this 2 × 10 A capability under recommended operating conditions.
Does the DA9214-XXFSC-A support remote voltage sensing for both output rails?
Yes, the DA9214-XXFSC-A provides full 4-point remote sensing: FBAP/FBAN for Buck A and FBBP/FBBN for Buck B. This allows precise point-of-load regulation independent of PCB trace resistance, maintaining ±1% static accuracy even with long or narrow routing paths. The DA9214-XXFSC-A implements dedicated sense amplifiers and feedback loops for each rail to ensure isolation and stability.
Can the DA9214-XXFSC-A operate with input voltages below 3.0 V?
Yes, the DA9214-XXFSC-A supports an input voltage range of 2.8 V to 5.5 V, making it compatible with partially discharged Li-ion batteries and low-voltage automotive domains. Operation at 2.8 V is validated across the full temperature range (-40 °C to +105 °C), with guaranteed 10 A output capability and stable 3 MHz switching - confirmed in Table 5 (Recommended Operating Conditions) of the DA9214-XXFSC-A datasheet.
How does Dynamic Voltage Control (DVC) function on the DA9214-XXFSC-A?
The DA9214-XXFSC-A supports DVC through two parallel mechanisms: register-based control via its I²C/SPI interface and direct analog voltage injection on the DVS pin. This allows real-time adjustment of either Buck A or Buck B output voltage in response to processor load changes - critical for DVFS in automotive SoCs. The DA9214-XXFSC-A's DVC circuitry maintains monotonicity and avoids glitches during transitions, as verified in functional test reports.
Is the DA9214-XXFSC-A pin-compatible with other devices in the DA92xx family?
No, the DA9214-XXFSC-A is not pin-compatible with DA9213-A or DA9215-A. While all three share the same 66-pin VFBGA package and ball pitch, their internal phase allocations differ significantly: DA9214-XXFSC-A assigns A1/A2 to Buck A and B1/B2 to Buck B, whereas DA9215-A reassigns B2 to Buck A. Pin functions like LX_B2 and FBBN have different roles across variants - confirmed in Table 1 and Figure 2 of the DA9214-XXFSC-A datasheet.
