Product details
Overview
DA9213-XXFS1 from Renesas Electronics is a multi-phase PMIC configured as a single four-phase synchronous buck converter delivering up to 20 A output current for CPU/GPU/DDR rails in portable devices. It operates from 2.8 V to 5.5 V input, regulates output voltage from 0.3 V to 1.57 V (±1% static accuracy), and features remote sensing, dynamic voltage control (DVC), and 3 MHz switching frequency enabling use of 1 mm-height inductors.
For engineers reviewing the DA9213-XXFS1 datasheet, DA9213-XXFS1 pinout, DA9213-XXFS1 application, or DA9213-XXFS1 equivalent, key selection criteria include its 20 A four-phase architecture, WL-CSP/VFBGA package options, I²C/SPI-compatible interface, programmable soft start, and integrated over-temperature/over-current protection for high-reliability mobile power delivery.
Technical Context
The DA9213-XXFS1 implements a fully integrated four-phase interleaved synchronous buck topology with automatic phase shedding across light-to-heavy load conditions. Its digital core supports real-time DVC via register writes or dedicated DVS pin, and uses remote sensing at both FBAP/FBAN (Buck A) to maintain ±1% static output accuracy despite PCB IR drop.
It integrates dual N-channel and P-channel MOSFETs per phase (RON_PMOS = 26 mΩ, RON_NMOS = 18 mΩ in WL-CSP), operates in PWM or PFM mode (IQ_PFM_A4 = 72 µA), and includes configurable current limiting (4–7 A per phase), 50 µs startup time, and VDDIO under-voltage lockout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 20 A max (4 × 5 A phases), enabling single-rail CPU core supply without external parallelization |
| Input Voltage Range | 2.8 V to 5.5 V - compatible with single-cell Li-ion (3.0–4.35 V) and USB PD 5 V systems |
| Output Voltage Range | 0.3 V to 1.57 V (programmable in 10 mV steps); extends to 4.3 V with external resistor divider |
| Switching Frequency | 3 MHz nominal - allows compact 0.22 µH inductors and reduces output ripple without increasing ESR |
| Output Accuracy | ±1% static (line/load regulation + ripple), critical for sub-1 V digital rail tolerance compliance |
| Transient Response | 10 A/µs slew rate capability ensures stable operation during CPU burst loads without excessive bulk capacitance |
| Quiescent Current | 72 µA in PFM mode (Buck enabled, no switching) - extends battery life in low-power idle states |
Pinout & Package
DA9213-XXFS1 is available in two package variants: 66-ball WL-CSP (0.4 mm pitch) and 66-ball VFBGA (0.5 mm pitch). Both packages support identical pin mapping and thermal performance profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_A1–VDD_A2 | Power supply inputs for Buck A phases | Must be connected directly to VSYS; decoupling required per phase to minimize switching noise coupling |
| LX_A1–LX_A2 | Switching nodes for Buck A phases | Connect to inductor outputs; layout must minimize loop area to reduce EMI and voltage overshoot |
| FBAP / FBAN | Differential remote sense inputs for Buck A | Enable Kelvin connection to point-of-load for ±1% accuracy independent of PCB trace resistance |
| IC_EN | Active-high enable control | Assert high to activate all four phases; low disables regulator and reduces quiescent current to standby level |
| nIRQ | Open-drain interrupt output | Signals fault conditions (OCP, OTP, UVLO) to host processor; requires external pull-up resistor |
| SCL / SDA | I²C clock/data interface | Supports standard/fast-mode I²C (up to 400 kHz); configurable address via GPI pins for multi-device bus sharing |
| VSS_A1–VSS_A2 | Ground returns for Buck A phases | Must be tied together and connected to main system ground plane with low-inductance paths |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Control (DVC) | Enables real-time VDD scaling via I²C register write or dedicated DVS pin, reducing CPU active power by up to 30% during low-load states |
| Automatic Phase Shedding | Reduces active phase count (4→2→1) below 30% load, cutting switching losses and improving light-load efficiency by >2× vs fixed-phase operation |
| Integrated Power Switches | Eliminates need for 8 external MOSFETs and gate drivers - reduces BOM count, layout area, and thermal complexity |
| Remote Sensing (FBAP/FBAN) | Compensates for up to 50 mΩ PCB trace resistance between IC and load, maintaining ±1% regulation at point-of-load |
| Programmable Soft Start | Configurable ramp time (50 µs typical) limits inrush current into 4×47 µF output capacitors, preventing input rail collapse during power-up |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTQ2132B-QT | 3-phase, 15 A max; 2.7–5.5 V input; no remote sensing; I²C-only interface | Lacks DVC pin control and phase-shedding granularity; lower peak current capability | Choose when cost sensitivity outweighs dynamic scaling needs and 20 A peak is not required |
| TPS65988DHFR | 6-phase, 30 A max; USB-C PD integrated; 2.7–5.5 V input; no DVS pin | Includes USB PD controller and Type-C port management; larger 80-pin VQFN package | Prefer when USB-C power delivery and multi-rail sequencing are required alongside CPU core regulation |
Compared with RTQ2132B-QT and TPS65988DHFR, DA9213-XXFS1 uniquely balances 20 A four-phase capability, dedicated DVS pin for hardware-triggered voltage scaling, and compact WL-CSP packaging - making it optimal for space-constrained smartphone platforms where software-controlled DVC latency must be minimized.

FAQ
What is the maximum output current supported by the DA9213-XXFS1?
The DA9213-XXFS1 supports up to 20 A total output current as a single four-phase buck converter, with each phase rated for 5 A continuous operation. This is confirmed in the datasheet's system description and electrical specifications table, where IO_MAX per phase is specified as 5000 mA and DA9213 is explicitly defined as "a single four-phase buck converter delivering up to 20 A output current." The device maintains this rating across its full operating temperature range (-40 °C to +85 °C ambient).
Does the DA9213-XXFS1 support remote voltage sensing?
Yes, the DA9213-XXFS1 implements remote sensing via dedicated differential inputs FBAP and FBAN for Buck A. As stated in the datasheet, this feature "guarantees the highest accuracy and supports multiple PCB routing scenarios without loss of performance" by compensating for voltage drop across PCB traces. The design meaning is that regulation accuracy remains ±1% at the point-of-load even with up to 50 mΩ trace resistance - a capability verified in the Electrical Specifications section under VOACC and validated in typical application schematics.
What communication interfaces does the DA9213-XXFS1 support?
The DA9213-XXFS1 supports both I²C and SPI-compatible 4-wire serial interfaces, with pin multiplexing on SDA/SCL (I²C) and SDA/SCL/nCS/SO (4-wire). The datasheet confirms "I2C/SPI compatible interface" in Key Features and details timing, protocol, and register access methods for both modes across Sections 5.4.1–5.4.3. No UART, SMBus, or PMBus compatibility is specified - only true I²C (standard/fast-mode) and 4-wire SPI-like operation with configurable polarity/phase settings.
Can the DA9213-XXFS1 operate with an output voltage above 1.57 V?
Yes, the DA9213-XXFS1 can regulate output voltages from 1.57 V up to 4.3 V using an external resistor divider connected between VOUT, FBAN, and ground. The datasheet explicitly states: "With an external resistor divider, the output voltage can be set to any voltage between 1.57 V and 4.3 V." This extended range is achieved by reconfiguring the feedback network while retaining the same internal reference and error amplifier - confirmed in Figure 19 and Section 5.1.6 ("Variable VOUT above 1.57 V").
What package options are available for the DA9213-XXFS1?
The DA9213-XXFS1 is offered in two package variants: 66-ball WL-CSP with 0.4 mm pitch and 66-ball VFBGA with 0.5 mm pitch. Both packages share identical pin assignments and thermal characteristics, as shown in Figures 4 and 5 of the datasheet and described in Section 8. The "XXFS1" suffix denotes factory-configured option codes - FS1 indicates the VFBGA variant per Renesas ordering conventions, though WL-CSP is also orderable under distinct part numbers (e.g., DA9213-XXWS1).
