Product details
Overview
DA9215-XXFSC-AT from Renesas Electronics is an AEC-Q100 Grade 2 automotive power management IC integrating a three-phase 15 A buck converter (Buck A) and a single-phase 5 A buck converter (Buck B), operating from 2.8 V to 5.5 V input, delivering programmable output voltages from 0.3 V to 1.57 V (or up to 4.3 V with external resistor divider), and featuring 3 MHz switching frequency, ±1% static voltage accuracy, and remote sensing for point-of-load regulation - deployed in ADAS domain controllers and automotive display clusters.
For engineers reviewing the DA9215-XXFSC-AT datasheet, DA9215-XXFSC-AT pinout, DA9215-XXFSC-AT application, or DA9215-XXFSC-AT equivalent, key selection criteria include multi-rail dynamic voltage control (DVC) via I²C/SPI, phase shedding for light-load efficiency, integrated power switches eliminating external FETs, -40 °C to +105 °C operation, and 66-pin VFBGA 0.5 mm pitch packaging compatible with automotive PCB layout constraints.
Technical Context
The DA9215-XXFSC-AT implements two independent synchronous buck regulators: Buck A uses three phases (A1, A2, B2) for 15 A output with automatic phase shedding; Buck B uses one phase (B1) for 5 A output. Both support Dynamic Voltage Control (DVC) via register writes or dedicated DVS pin, enabling real-time supply adaptation to CPU/GPU load states.
It features dual-mode operation (PWM and PFM), 3 MHz fixed-frequency switching enabling compact 0.22 µH inductors, integrated over-temperature and over-current protection, VDDIO under-voltage lockout, and configurable I²C address selection via GPI pins - all within a single 66-pin VFBGA package qualified per AEC-Q100 Grade 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V - supports direct connection to automotive 3.3 V/5 V rails and Li-ion battery systems without pre-regulation. |
| Output Current Capability | 15 A (3-phase Buck A) + 5 A (1-phase Buck B) - enables dual-rail CPU core and I/O voltage supply from one PMIC. |
| Switching Frequency | 3 MHz nominal - permits use of low-profile (1 mm height) inductors and reduces output capacitor count. |
| Voltage Accuracy | ±1% static (DC), ±3% dynamic (transient) - ensures stable core voltage under fast load steps up to 10 A/µs. |
| Operating Temperature | -40 °C to +105 °C ambient - meets automotive cabin and engine bay thermal requirements per AEC-Q100 Grade 2. |
| Interface Protocol | I²C/SPI-compatible 2-/4-wire bus - allows flexible host processor integration with configurable slave address and interrupt signaling. |
| Protection Features | Integrated over-current, over-temperature, and VDDIO UVLO - eliminates need for external fault-sensing circuitry. |
Pinout & Package
DA9215-XXFSC-AT is housed in a 66-pin Very Thin Fine-Pitch Ball Grid Array (VFBGA) package with 0.5 mm pitch, designed for high-density automotive PCB layouts and thermal performance up to 125 °C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1, LX_A2, LX_B2 | Switching node (Buck A phases 1 & 2, Buck A phase 3) | High-frequency PWM outputs driving external inductors; require tight layout and local decoupling. |
| LX_B1 | Switching node (Buck B phase 1) | Dedicated node for 5 A single-phase rail; isolated routing prevents coupling into Buck A paths. |
| FBAP / FBAN | Remote sense inputs (Buck A) | Enable Kelvin sensing at CPU VDD rail to compensate for PCB IR drop and maintain ±1% regulation. |
| FBBP / FBBN | Remote sense inputs (Buck B) | Support precision regulation of auxiliary rail (e.g., DDR I/O or GPU memory interface) independent of Buck A. |
| IC_EN | Enable control input | Active-high logic signal controlling global PMIC startup/shutdown sequence with internal soft-start timing. |
| nIRQ | Interrupt output | Open-drain signal asserting on fault conditions (OCP, OTP, UVLO) for host processor event-driven response. |
| SDA / SCL / nCS / SO | I²C/SPI interface signals | Support both 2-wire (I²C) and 4-wire (SPI-like) protocols; nCS polarity and clock phase configurable via OTP. |
| GPI0 / GPI1 / GPIO2 | General-purpose inputs/outputs | Configurable as DVC trigger inputs, status indicators, or system-level control signals (e.g., power-good enable). |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Control (DVC) | Real-time VOUT adjustment via register write or dedicated DVS pin - reduces CPU dynamic power by >20% during low-load states. |
| Automatic Phase Shedding | Reduces active phases in Buck A from 3 to 1 under light load - improves light-load efficiency by up to 15% vs fixed-phase operation. |
| Integrated Power Switches | On-resistance of 27 mΩ (PMOS) and 19 mΩ (NMOS) per phase - eliminates external FETs and Schottky diodes, saving >12 mm² PCB area. |
| Remote Sensing (PoL) | Dual differential sense pairs (FBAP/FBAN, FBBP/FBBN) - maintains ±1% output accuracy despite >100 mΩ PCB trace resistance. |
| Programmable Soft Start | Configurable startup time (50–500 µs) via register - limits inrush current to <2 A during rail activation, preventing input voltage sag. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436-AEC1 | Single 12 A 3-phase buck; no secondary buck rail; 2.5–18 V input; no DVC pin; I²C-only interface | Supports higher VIN but lacks dual-rail flexibility; requires external sequencing for auxiliary rails | Choose when only one high-current rail is needed and input exceeds 5.5 V (e.g., 12 V battery-fed systems). |
| TPS65917-Q1 | 7-rail PMIC including LDOs, RTC, and charger; 3 A max buck per rail; 2.7–5.5 V input; SPI-only interface | Broad feature set for full system power, but lower per-rail current and no phase shedding | Prefer when integrating multiple low-power rails (e.g., USB PHY, CAN transceiver, sensor bias) alongside main SoC supplies. |
Compared with MPQ4436-AEC1 and TPS65917-Q1, DA9215-XXFSC-AT uniquely delivers asymmetric dual-buck capability (15 A + 5 A) with hardware DVC support and phase shedding - making it optimal for cost- and space-constrained ADAS processors needing adaptive core/memory voltage scaling without external controllers.

FAQ
What is the maximum output current supported by DA9215-XXFSC-AT per buck channel?
The DA9215-XXFSC-AT supports up to 15 A from its three-phase Buck A channel and up to 5 A from its single-phase Buck B channel. These ratings assume proper thermal management, recommended external components (0.22 µH inductors, 47 µF per phase output capacitance), and operation within the -40 °C to +105 °C ambient range. Peak current limit per phase is programmable from 4 A to 7 A.
Does DA9215-XXFSC-AT support remote voltage sensing for both buck regulators?
Yes, DA9215-XXFSC-AT provides dedicated remote sense inputs for both regulators: FBAP/FBAN for Buck A and FBBP/FBBN for Buck B. This enables true point-of-load regulation by compensating for voltage drop across PCB traces, ensuring ±1% output accuracy even with >100 mΩ interconnect resistance - critical for high-current automotive SoC applications.
How does Dynamic Voltage Control (DVC) function on DA9215-XXFSC-AT?
DA9215-XXFSC-AT implements DVC through two independent methods: (1) register-based control via I²C/SPI interface for precise software-defined voltage steps, and (2) hardware-triggered adjustment using the dedicated DVS input pin. This allows real-time voltage scaling synchronized to processor load states - reducing dynamic power consumption by up to 25% during low-activity periods without host CPU intervention.
What package type and pin count does DA9215-XXFSC-AT use?
DA9215-XXFSC-AT uses a 66-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA) package with 0.5 mm pitch. The package measures 5.0 mm × 5.0 mm × 0.55 mm and is qualified to AEC-Q100 Grade 2 standards. Pin assignments are fully documented in the Renesas datasheet R16DS0618EJ0231, including dedicated LX nodes, sense inputs, and configurable interface signals.
Is DA9215-XXFSC-AT compatible with both I²C and SPI communication interfaces?
Yes, DA9215-XXFSC-AT supports both 2-wire (I²C-compatible) and 4-wire (SPI-compatible) serial interfaces. It accepts standard I²C addressing and timing, and also operates in 4-wire mode with configurable nCS polarity and clock phase (CPOL/CPHA). Interface selection is determined by hardware configuration at power-up and can be verified via register reads.
