Product details
Overview
DA9213-XXFSC 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 (extendable to 4.3 V with external divider), and features 3 MHz switching frequency, ±1% static output accuracy, and remote sensing at point of load.
For engineers reviewing the DA9213-XXFSC datasheet, DA9213-XXFSC pinout, DA9213-XXFSC application, or DA9213-XXFSC equivalent, key selection criteria include its 20 A four-phase architecture, I²C/SPI-compatible interface with configurable address, dynamic voltage control (DVC) support, integrated over-temperature/over-current protection, and WL-CSP/VFBGA package options for space-constrained mobile designs.
Technical Context
The DA9213-XXFSC implements a fully integrated four-phase interleaved synchronous buck topology with programmable phase shedding across light-to-heavy loads. Its digital core supports real-time DVC via register writes or dedicated DVS pin, enabling adaptive voltage scaling synchronized with processor workload states.
It integrates dual power stages per phase (PMOS/NMOS), on-die current sensing, and precision remote feedback (FBAP/FBAN) to maintain ±1% static regulation under line/load transients up to 10 A/µs. The 3 MHz fixed-frequency PWM mode ensures compatibility with low-profile 0.22 µH inductors while minimizing output capacitance requirements.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_A1–VDD_A2 VDD_B1–VDD_B2 |
Phase supply inputs | Four independent 2.8–5.5 V input rails for each buck phase - must be connected to VSYS with local decoupling |
| LX_A1–LX_A2 LX_B1–LX_B2 |
Switching node outputs | Four high-side/lower-side node connections - drive external inductors and require low-inductance layout to minimize EMI |

| nIRQ | Interrupt output | Open-drain status signal indicating fault conditions (OCP, OTP, UVLO) or DVC completion events |
| SDA / SCL nCS / SO / GPIx |
Communication & GPIO | Configurable I²C/SPI interface plus 5 general-purpose I/Os - supports host-controlled sequencing and system-level monitoring |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Control (DVC) | Hardware- and register-controlled adaptive output adjustment - synchronizes rail voltage with CPU DVFS states to reduce dynamic power by up to 30% |
| Automatic Phase Shedding | Real-time load-dependent phase enable/disable - maintains >85% efficiency from 10 mA to 20 A without manual mode switching |
| Integrated Power Switches | Low RDS(on) PMOS (26 mΩ WL-CSP) and NMOS (18 mΩ WL-CSP) per phase - eliminates external FETs and Schottky diodes |
| Remote Sensing Architecture | Differential feedback (FBAP/FBAN) referenced at point-of-load - compensates for PCB IR drop to ensure ±1% regulation at load, not IC pin |
| Programmable Soft Start | Configurable ramp time (50 µs typical) - limits inrush current into bulk capacitors and prevents input voltage sag during power-up |
| Thermal & Electrical Protection | On-die temperature sensor with programmable OTP threshold, per-phase OCP with 4000–7000 mA range, and VDDIO UVLO - no external components required |

FAQ
What is the maximum output current capability of the DA9213-XXFSC?
The DA9213-XXFSC delivers up to 20 A continuous output current as a single four-phase buck converter, with each phase rated for 5 A. 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 operating "as a single four-phase buck converter delivering up to 20 A output current." The DA9213-XXFSC achieves this without external FETs due to fully integrated power stages.
Does the DA9213-XXFSC support dynamic voltage scaling (DVS) via hardware pin or only through registers?
Yes, the DA9213-XXFSC supports Dynamic Voltage Control (DVC) via both methods: direct register writes over I²C/SPI and through a dedicated DVS input pin. The datasheet confirms this dual-mode capability in the overview section and functional description, stating DVC "supports adaptive adjustment… either via direct register writes… or via an input pin." This allows system designers to implement either firmware-controlled or hardware-synchronized voltage scaling depending on SoC interface availability.
What package options are available for the DA9213-XXFSC, and are they pin-compatible?
The DA9213-XXFSC is offered in two mechanically distinct but functionally identical packages: 66-ball WL-CSP with 0.4 mm pitch and 66-ball VFBGA with 0.5 mm pitch. Pin assignments are identical across both packages as shown in Figures 4 and 5 of the datasheet, and Table 2 lists all pin functions without package differentiation. However, they are not physically interchangeable due to different ball pitch and mounting requirements - board layout must match the selected variant.
Can the DA9213-XXFSC regulate output voltages above 1.57 V, and how is that achieved?
Yes, the DA9213-XXFSC supports output voltages from 1.57 V up to 4.3 V using an external resistor divider connected between VOUT and the FBAN pin, with FBAP tied to VOUT. This configuration is explicitly documented in the datasheet's overview and Section 5.1.6 ("Variable VOUT above 1.57 V"). The internal reference remains fixed at 0.6 V, and the divider ratio scales the feedback loop accordingly - enabling flexible use for DDR, I/O, or auxiliary rails beyond core CPU voltage ranges.
How does the DA9213-XXFSC handle thermal protection, and is the threshold configurable?
The DA9213-XXFSC includes integrated over-temperature protection (OTP) with a default trip point of 125 °C, as specified in Table 14 of the datasheet. While the primary threshold is fixed, the device provides register-accessible temperature supervision data and allows configuration of interrupt behavior (nIRQ assertion) upon detection. It does not support user-programmable OTP thresholds - the protection is hard-coded for reliability in portable applications where junction temperature must remain below 150 °C absolute maximum.
