Product details
Overview
DA9215-XXFS1-A from Renesas Electronics is an automotive-grade 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 remote sensing, dynamic voltage control (DVC), and I²C/SPI-compatible interface for CPU/GPU/DDR rail regulation in ADAS and infotainment systems.
For engineers reviewing the DA9215-XXFS1-A datasheet, DA9215-XXFS1-A pinout, DA9215-XXFS1-A application, or DA9215-XXFS1-A equivalent, key selection considerations include phase allocation (Buck A: phases A1, A2, B2; Buck B: phase B1), ±1% static output accuracy, 3 MHz switching frequency enabling low-profile inductor use, AEC-Q100 Grade 2 qualification, and 66-pin VFBGA 0.5 mm pitch packaging.
Technical Context
The DA9215-XXFS1-A implements two independent synchronous buck regulators: Buck A uses three phases (A1, A2, B2) with automatic phase shedding and fast transient response (±2.5% load regulation at 5 A/500 ns), while Buck B uses one dedicated phase (B1) supporting up to 5 A with separate current limit programming. Both rails support dynamic voltage scaling via register writes or DVS pin control.
Its digital core includes OTP memory, configurable I²C address via GPI, integrated over-temperature and over-current protection, VDDIO under-voltage lockout, and dual-mode operation (PWM/PFM) - with PFM quiescent current as low as 130 µA for both Buck A and Buck B enabled - all operating across –40 °C to +105 °C ambient.
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 Voltage Range | 0.3 V to 1.57 V programmable; extends to 4.3 V with external resistor divider - enables direct DDR, GPU core, and I/O rail regulation. |

| Transient Response | ±2.5% for Buck A (0–5 A, 500 ns), ±2.5% for Buck B (0–2.5 A, 200 ns) - maintains tight regulation during CPU/GPU burst loads. |
| Operating Temperature | –40 °C to +105 °C ambient - qualified per AEC-Q100 Grade 2 for under-hood and dashboard-mounted automotive electronics. |
| Protection Features | Integrated over-current, over-temperature, and VDDIO UVLO - eliminates need for external fault-sensing circuitry in safety-critical systems. |
Pinout & Package
DA9215-XXFS1-A 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. The package supports reflow soldering per JEDEC J-STD-020 and includes exposed thermal pad for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| VDD_A1/VDD_A2/VDD_B1/VDD_B2 | Phase supply pins | Each connects directly to VSYS to power respective internal high-side/low-side FET drivers - no external bootstrap components required. |
| SDA / SCL / nCS | I²C/SPI-compatible interface | Supports standard 2-wire (I²C) or 4-wire (SPI-like) communication with configurable address via GPI0 for multi-PMIC systems. |
| nIRQ | Interrupt output | Open-drain signal indicating fault conditions (OCP, OTP, UVLO) or DVC completion - simplifies host processor monitoring. |
| IC_EN | Global enable input | Active-high logic control to power up/down entire device - enables system-level sequencing with other PMICs or processors. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Control (DVC) | Adjusts Buck A output in real time via register write or dedicated DVS pin - reduces CPU power consumption during low-load states without software overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail automotive PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436-AEC1 | Single 12 A monolithic buck; no secondary rail or DVC pin; requires external sequencing IC for multi-rail coordination. | Suitable only for single-rail CPU cores; lacks independent Buck B for DDR/I/O or remote sensing on secondary output. | Select when cost-sensitive single-rail design suffices and DVC coordination is handled externally. |
| TPS6594212RGERQ1 | Four-buck PMIC with 6 A/4 A/3 A/3 A outputs; supports ASIL-B functional safety but no 3 MHz switching or integrated phase shedding logic. | Better for ASIL-B systems needing diagnostic coverage; less optimal for high-transient, space-constrained IVI displays due to lower switching frequency (2.1 MHz). | Select when ISO 26262 compliance is mandatory and board area is less constrained than for DA9215-XXFS1-A's 3 MHz solution. |
Compared with MPQ4436-AEC1 and TPS6594212RGERQ1, DA9215-XXFS1-A uniquely combines dual independent buck regulation (15 A + 5 A), 3 MHz switching for minimal inductor height, and hardware DVC support - making it optimal for compact, high-transient automotive SoC power delivery where secondary rail independence and fast voltage scaling are critical.

FAQ
What is the exact phase configuration of DA9215-XXFS1-A per the datasheet?
The DA9215-XXFS1-A implements a three-phase Buck A regulator using switching nodes LX_A1, LX_A2, and LX_B2, and a single-phase Buck B regulator using LX_B1. This allocation is fixed and distinct from DA9213-A (four-phase Buck A) and DA9214-A (dual dual-phase Bucks); Table 1 and Figure 3 in R16DS0618EJ0231 confirm this mapping. Each phase has dedicated VDD and VSS pins, and Buck B operates independently with its own current limit and remote sense pair (FBBP/FBBN).
Does DA9215-XXFS1-A support remote sensing on both Buck A and Buck B outputs?
Yes, DA9215-XXFS1-A supports full remote sensing on both outputs: Buck A uses FBAP (positive) and FBAN (negative) pins, while Buck B uses FBBP (positive) and FBBN (negative) pins. As specified in Table 2 (Page 9) and Section 5.2.1, these differential sense inputs connect directly to the load to compensate for PCB trace resistance, enabling ±1% static accuracy at point-of-load - critical for DDR and GPU core rails where voltage margin is tight.
What is the minimum output voltage step size programmable for DA9215-XXFS1-A?
The DA9215-XXFS1-A supports 10 mV output voltage steps across its programmable range of 0.3 V to 1.57 V, as explicitly stated in Note 1 of Table 6 (Page 12). This granularity allows precise tuning for process-voltage corners and SoC-specific requirements - for example, setting 0.85 V for an ARM Cortex-A76 core or 1.1 V for an image signal processor - without requiring external resistor dividers.
Can DA9215-XXFS1-A operate in PFM mode with both Buck A and Buck B enabled simultaneously?
Yes, DA9215-XXFS1-A supports simultaneous PFM operation of Buck A and Buck B, with a total quiescent current of 130 µA (typical) at VDD = 3.7 V, as documented in Table 6 (IQ_PFM_A3B1, Page 14). This mode activates automatically at light loads and is ideal for always-on automotive functions like telematics wake-up receivers, where ultra-low standby power is essential and load transients remain within Buck B's 2.5 A capability.
Is the 66-pin VFBGA package of DA9215-XXFS1-A compatible with standard automotive reflow profiles?
Yes, the DA9215-XXFS1-A's 66-pin VFBGA package complies with JEDEC J-STD-020 moisture sensitivity level (MSL) 3 and supports standard lead-free reflow profiles up to 260 °C peak temperature. Package mechanical data in Section 8.1 (Page 58) confirms 0.5 mm pitch, 4.0 × 4.0 mm body size, and thermal pad design optimized for automotive PCB thermal vias - enabling reliable assembly in high-volume automotive manufacturing lines.
