Product details
Overview
DA9214-XXFSC-AT 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 voltage (extendable to 4.3 V via resistor divider), and features 3 MHz switching frequency, ±1% static output accuracy, and AEC-Q100 Grade 2 qualification.
For engineers reviewing the DA9214-XXFSC-AT datasheet, DA9214-XXFSC-AT pinout, DA9214-XXFSC-AT application, or DA9214-XXFSC-AT equivalent, key selection criteria include dual-buck phase allocation (Buck A: phases A1/A2; Buck B: phases B1/B2), remote sensing capability at point-of-load (FBAP/FBAN, FBBP/FBBN), I²C/SPI-compatible interface with configurable address, and integrated over-temperature/over-current protection without external sensing components.
Technical Context
The DA9214-XXFSC-AT implements two independent synchronous buck converters-Buck A (phases A1/A2) and Buck B (phases B1/B2)-each operating in PWM or PFM mode with automatic phase shedding. Its 3 MHz nominal switching frequency enables use of low-profile 0.22 µH inductors and reduces output capacitance requirements.
Dynamic Voltage Control (DVC) allows real-time output voltage adjustment via register writes or dedicated DVS pin, supporting adaptive power management for multi-core processors. Remote sensing on both rails (via differential FBxP/FBxN pairs) compensates for PCB IR drop, maintaining ±1% static accuracy across load and line variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V - supports Li-ion battery-powered automotive systems and wide-input low-voltage rails. |
| Output Current Capability | 2 × 10 A - independent dual-buck architecture supplies separate high-current rails for processor cores and memory subsystems. |
| Switching Frequency | 3 MHz - enables compact magnetics (0.22 µH) and fast transient response (10 A/µs). |
| Output Voltage Range | 0.3 V to 1.57 V (programmable); up to 4.3 V with external resistor divider - covers core logic, GPU, and DDR I/O supply requirements. |
| Output Accuracy | ±1% (static), ±3% (dynamic) - ensures stable voltage regulation under rapid load transients typical in automotive SoCs. |

Pinout & Package
DA9214-XXFSC-AT is housed in 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1, LX_A2 | Switching node (Buck A) | Connects to phase-inductor outputs for Buck A; requires low-ESR ceramic capacitors and tight layout for EMI control. |
| LX_B1, LX_B2 | Switching node (Buck B) | Connects to phase-inductor outputs for Buck B; electrically isolated from Buck A nodes to prevent cross-coupling. |
| FBAP / FBAN | Differential sense input (Buck A) | Remote sensing pair for Buck A output; placed at point-of-load to reject PCB trace resistance error. |
| FBBP / FBBN | Differential sense input (Buck B) | Remote sensing pair for Buck B output; enables independent closed-loop regulation per rail. |
| VDD_A1/VDD_A2/VDD_B1/VDD_B2 | Phase supply inputs | Each tied directly to VSYS; internal power switches eliminate need for external FETs or Schottky diodes. |
| IC_EN | Enable control | Active-high signal enabling full device operation; supports sequencing with other system power rails. |
| nIRQ | Interrupt output | Open-drain flag signaling fault conditions (OCP, OTP, UVLO) to host processor or safety controller. |
| SDA / SCL / nCS | I²C/SPI interface | Supports 2-wire (I²C) or 4-wire (SPI) communication; GPI-configurable I²C address enables multi-PMIC bus sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Switches | On-die PMOS (27 mΩ) and NMOS (19 mΩ) per phase eliminate external FETs, reducing BOM count and layout complexity. |
| Dynamic Voltage Control (DVC) | Real-time VOUT adjustment via register write or analog DVS pin - enables energy-efficient DVFS for automotive application processors. |
| Automatic Phase Shedding | Reduces active phases under light load to maintain >85% efficiency down to 2 mA - critical for low-power standby modes in telematics. |
| Remote Sensing (Dual Rail) | Independent FBxP/FBxN pairs per buck ensure ±1% regulation accuracy despite PCB voltage drop - essential for sub-1 V core supplies. |
| Programmable Soft Start | Configurable startup ramp (50–500 µs) limits inrush current into bulk capacitance - prevents input rail collapse during cold boot. |

FAQ
What is the maximum output current per buck regulator in DA9214-XXFSC-AT?
The DA9214-XXFSC-AT integrates two independent dual-phase buck regulators: Buck A (phases A1/A2) and Buck B (phases B1/B2), each capable of delivering up to 10 A continuous output current. This is achieved using fully integrated power switches and 3 MHz switching, enabling high current density without external FETs. The DA9214-XXFSC-AT datasheet confirms this rating under recommended operating conditions (TA = −40 °C to +105 °C, VIN = 2.8–5.5 V).
Does DA9214-XXFSC-AT support remote sensing for both output rails?
Yes, the DA9214-XXFSC-AT supports true differential remote sensing on both output rails: FBAP/FBAN for Buck A and FBBP/FBBN for Buck B. Each pair connects directly to the point-of-load to compensate for PCB trace resistance, maintaining ±1% static output accuracy regardless of board layout. This capability is explicitly documented in the DA9214-XXFSC-AT datasheet Section 2.2 and Figure 2 (system diagram).
What communication interfaces does DA9214-XXFSC-AT support?
The DA9214-XXFSC-AT supports both 2-wire (I²C-compatible) and 4-wire (SPI-compatible) digital interfaces via shared pins SDA/SCL (2-wire) and SDA/SCL/nCS/SO (4-wire). Address configuration is handled through GPI pins, allowing multiple DA9214-XXFSC-AT devices on the same bus. Interface timing and register access protocols are fully specified in Sections 5.4.1–5.4.3 of the DA9214-XXFSC-AT datasheet.
Is DA9214-XXFSC-AT qualified for automotive use?
Yes, the DA9214-XXFSC-AT is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C ambient), with integrated over-temperature protection, over-current protection, and VDDIO under-voltage lockout. It meets automotive reliability and safety requirements for use in ADAS, infotainment, and telematics systems. This qualification is stated on page 1 of the DA9214-XXFSC-AT datasheet and verified in Table 14 (over-temperature thresholds) and Section 3.2.
Can DA9214-XXFSC-AT generate output voltages above 1.57 V?
Yes, the DA9214-XXFSC-AT supports output voltages from 0.3 V to 1.57 V via internal DAC programming, and up to 4.3 V using an external resistor divider connected between VOUT and FBAN. The divider ratio is calculated per Figure 17 in the DA9214-XXFSC-AT datasheet, and the extended range applies to both Buck A and Buck B outputs independently.
