Product details
Overview
DA9214-XXUP6 from Renesas Electronics is a dual-output, dual-phase-per-rail PMIC delivering 2 × 10 A output current for CPU/GPU and DDR memory rails in portable devices. It operates from 2.8 V to 5.5 V input, regulates each output from 0.3 V to 1.57 V (±1% static accuracy), and supports remote sensing at point-of-load with 3 MHz switching frequency enabling 1 mm-height inductors.
For engineers reviewing the DA9214-XXUP6 datasheet, DA9214-XXUP6 pinout, DA9214-XXUP6 application, or DA9214-XXUP6 equivalent, key selection criteria include its two independent 10 A buck converters, I²C/SPI-compatible interface with configurable address via GPI, dynamic voltage control (DVC) support, and integrated over-temperature/over-current protection without external sensing components.
Technical Context
The DA9214 integrates two independent dual-phase buck converters-Buck A (phases A1/A2) and Buck B (phases B1/B2)-each capable of 10 A output with automatic phase shedding and PWM/PFM mode transition. Its digital core implements register-based DVC control, soft-start timing (50 µs to 1.0 V), and programmable current limits (4–7 A per phase).
Remote sensing is implemented via dedicated FBAP/FBAN (Buck A) and FBBP/FBBN (Buck B) analog inputs, supporting accurate regulation under PCB trace IR drop. The device uses fully integrated power switches (26 mΩ PMOS / 18 mΩ NMOS per phase in WL-CSP) and supports both 2-wire (I²C) and 4-wire (SPI) interfaces with nCS/GPI4 and SDA/SO GPIO flexibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V - compatible with single-cell Li-ion battery systems and wide-input industrial rails. |
| Output Current Capability | 2 × 10 A - two independent high-current rails for CPU core + GPU or DDR VDDQ/VDDIO separation. |
| Output Voltage Range | 0.3 V to 1.57 V (programmable in 10 mV steps); up to 4.3 V with external resistor divider - supports modern low-voltage SoCs and legacy I/O rails. |
| Switching Frequency | 3 MHz nominal - enables compact 0.22 µH inductors and reduces output capacitance footprint vs. lower-frequency PMICs. |
| Output Voltage Accuracy | ±1% (static), ±3% (dynamic) - ensures stable core voltage under fast load transients (10 A/µs capability). |
| Operating Temperature | −40 °C to +85 °C ambient - qualified for smartphone, tablet, and mobile computing thermal environments. |
| Interface Protocol | I²C/SPI-compatible 2-wire or 4-wire bus - allows host processor integration without custom driver development. |
Pinout & Package
DA9214-XXUP6 is available in 66-ball WL-CSP (0.4 mm pitch) and 66-ball VFBGA (0.5 mm pitch) packages. Pin functions are identical across both packages; ball map follows JEDEC-standard layout per Figures 4 and 5 of R16DS0598EJ0361.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1, LX_A2 | Switching node (Buck A phases) | Connects to external inductor; requires low-inductance layout to minimize EMI and switching losses. |
| LX_B1, LX_B2 | Switching node (Buck B phases) | Independent high-side/lower-side node pair for second regulated rail; isolated routing recommended. |
| FBAP / FBAN | Remote sense inputs (Buck A) | Direct connection to load-side feedback points enables precise regulation despite PCB trace resistance. |
| FBBP / FBBN | Remote sense inputs (Buck B) | Enables independent closed-loop control for second rail; NC on DA9213 but functional on DA9214/DA9215. |
| VDD_A1–VDD_A2 / VDD_B1–VDD_B2 | Phase supply pins | Each tied to VSYS; decoupling required per phase to suppress high di/dt noise coupling. |
| IC_EN | Enable input | Active-high logic control for full system power sequencing; supports hardware-initiated rail enable/disable. |
| nIRQ | Interrupt output | Open-drain signal indicating fault conditions (OCP, OTP, UVLO) or DVC completion events. |
| SDA / SCL / nCS / SO | Communication interface | Supports I²C (SDA/SCL) or SPI (nCS/SO/SDA/SCL) with configurable address via GPI0 - eliminates need for level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10 A buck regulators | Enables separate, dynamically controlled power domains for CPU cores and GPU or DDR memory subsystems. |
| Dynamic Voltage Control (DVC) | Allows real-time VOUT adjustment via register write or dedicated DVS pin - essential for DVFS in application processors. |
| Remote sensing per rail | Compensates for up to 50 mΩ PCB trace resistance between IC and load, maintaining ±1% regulation accuracy at point-of-load. |
| Integrated power FETs | Eliminates need for external MOSFETs, Schottky diodes, or gate drivers - reduces BOM count and layout area by >30%. |
| Configurable I²C/SPI address | GPI0 selects one of two I²C addresses; allows co-location of multiple DA9214-XXUP6 units on same bus without address conflict. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output multi-phase buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP8859GQ-Z (Monolithic Power) | Single 20 A 4-phase buck; no dual-rail independence - shares inductor set and feedback path. | Suitable only when both rails require identical voltage and timing; cannot support independent DVC per rail. | Select MP8859GQ-Z only if system requires single-rail scaling and board space is more constrained than rail isolation. |
| TPS65988 (Texas Instruments) | USB-C PD + dual 10 A buck; includes Type-C controller, higher pin count (120-BGA), and larger footprint. | Targeted at docked/mobile hybrid devices needing USB-C power delivery negotiation alongside core power. | Choose TPS65988 only when USB-C PD functionality is mandatory; DA9214-XXUP6 offers superior integration density for pure DC-DC applications. |
Compared with MP8859GQ-Z and TPS65988, DA9214-XXUP6 uniquely delivers true dual-rail autonomy-separate feedback, independent DVC, and isolated phase control-within a 66-ball WL-CSP, making it optimal for space-constrained portable SoC power where rail isolation and dynamic scalability are critical.

FAQ
What is the maximum output current per rail supported by DA9214-XXUP6?
DA9214-XXUP6 supports up to 10 A per rail across two independent buck converters (Buck A and Buck B). Each rail uses two phases with integrated 26 mΩ PMOS and 18 mΩ NMOS switches, enabling continuous 10 A delivery with thermal derating applied above 70 °C ambient. Peak transient capability exceeds 12 A per rail under short-duration load steps.
Does DA9214-XXUP6 support remote sensing on both output rails?
Yes, DA9214-XXUP6 provides dedicated remote sense inputs for both rails: FBAP/FBAN for Buck A and FBBP/FBBN for Buck B. These differential analog inputs connect directly to the load-side feedback nodes, compensating for PCB trace resistance and ensuring ±1% static regulation accuracy at the point of load for each rail independently.
Can DA9214-XXUP6 operate with only one buck converter enabled?
Yes, DA9214-XXUP6 allows independent enable/disable control of Buck A and Buck B via register configuration. When only one buck is active, the unused phase drivers remain in high-impedance state, and the corresponding LX pins may be left unconnected or tied to ground through appropriate filtering. This supports flexible power sequencing and partial-system operation.
What package options are available for DA9214-XXUP6?
DA9214-XXUP6 is offered in two package variants: 66-ball WL-CSP (0.4 mm pitch, 2.7 mm × 3.2 mm body) and 66-ball VFBGA (0.5 mm pitch, 3.5 mm × 3.5 mm body). Both share identical pinout and electrical specifications; the WL-CSP variant is optimized for ultra-thin portable designs, while the VFBGA offers enhanced thermal dissipation for higher sustained loads.
How does Dynamic Voltage Control (DVC) function on DA9214-XXUP6?
DA9214-XXUP6 implements DVC through either register writes via its I²C/SPI interface or direct analog voltage injection on the DVS pin. The internal DAC converts the input into a precise offset to the reference voltage, enabling real-time adjustment of output voltage in 10 mV steps. This allows synchronized voltage scaling with processor workload changes without interrupting regulation stability.
