Product details
Overview
DA9214-XXUP2 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 electronics. 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 resistor divider), and features 3 MHz switching frequency, ±1% static output accuracy, and remote sensing at point of load.
For engineers reviewing the DA9214-XXUP2 datasheet, DA9214-XXUP2 pinout, DA9214-XXUP2 application, or DA9214-XXUP2 equivalent, this device supports I²C/SPI-compatible control, dynamic voltage control (DVC) via register or pin, programmable soft start, automatic phase shedding, and integrated over-temperature/over-current protection - critical for smartphone and tablet power architecture validation.
Technical Context
The DA9214-XXUP2 integrates two independent dual-phase buck converters (Buck A and Buck B), each supporting up to 10 A output with dedicated LX, VDD, and sense pins per phase. Its 3 MHz nominal switching frequency enables use of compact 0.22 µH inductors and low-profile layouts.
It implements remote sensing on both rails (FBAP/FBAN for Buck A; FBBP/FBBN for Buck B), supports 2-wire (I²C) and 4-wire (SPI-compatible) interfaces with configurable I²C address via GPI, and delivers fast transient response (≤±3.5% load regulation for 0–5 A step at 500 ns rise time).
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 Voltage Range | 0.3 V to 1.57 V (programmable in 10 mV steps); extends to 4.3 V with external resistor divider - covers core logic, GPU, and I/O supply requirements. |
| Max Output Current | 2 × 10 A - two independent 10 A rails support parallel processor cores and DDR memory subsystems. |
| Switching Frequency | 3 MHz - enables use of ultra-low-profile (1 mm height) inductors and reduces output capacitor count. |
| Output Accuracy | ±1% (static), ±3% (dynamic) - ensures stable voltage under load transients for high-performance SoCs. |
| Operating Temperature | −40 °C to +85 °C - qualified for consumer mobile and extended-temperature embedded applications. |
| Protection Features | Integrated over-current, over-temperature, and VDDIO under-voltage lockout - eliminates need for external fault monitoring circuitry. |
Pinout & Package
DA9214-XXUP2 is available in 66-ball WL-CSP (0.4 mm pitch) or 66-ball VFBGA (0.5 mm pitch) packages. Both variants share identical pin mapping and thermal performance characteristics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1, LX_A2 LX_B1, LX_B2 |
Switching node (x4) | High-frequency power switch outputs for Buck A (phases 1 & 2) and Buck B (phases 1 & 2); require low-ESR ceramic capacitors and tight layout to minimize EMI. |
| VDD_A1, VDD_A2 VDD_B1, VDD_B2 |
Power supply input (x4) | Phase-specific input rails tied to VSYS; decoupling required per phase to suppress switching noise coupling. |
| FBAP / FBAN FBBP / FBBN |
Remote sense inputs (x4) | Differential feedback nodes placed at point-of-load for Buck A and Buck B; enable <1% load regulation despite PCB IR drop. |
| IC_EN | Digital enable input | Active-high signal controlling global power-up sequence; synchronizes startup across both buck rails. |
| nIRQ | Interrupt output | Open-drain alert line signaling fault conditions (OCP, OTP, UVLO) to host processor without polling. |
| SDA / SCL nCS / SO / GPIOx |
Control interface I/O | Supports I²C (2-wire) or SPI-compatible (4-wire) communication; GPI-configurable I²C address allows multi-PMIC bus sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Control (DVC) | Enables real-time rail voltage adjustment via register write or dedicated DVS pin - reduces dynamic power consumption during CPU/GPU DVFS transitions. |
| Automatic Phase Shedding | Reduces active phases under light load (e.g., 2→1 phase per rail), cutting quiescent current to ≤106 µA (Buck A+B enabled, PFM mode) - extends battery life in idle states. |
| Integrated Power Switches | On-resistance of 26 mΩ (PMOS) / 18 mΩ (NMOS) per phase in WL-CSP - eliminates external FETs and Schottky diodes, reducing BOM count and board area. |
| Remote Sensing Architecture | Dedicated differential sense pairs (FBAP/FBAN, FBBP/FBBN) compensate for PCB trace resistance - maintains ±1% regulation accuracy at point-of-load under full 10 A load. |
| Configurable Soft Start | Programmable startup ramp (e.g., 50 µs to reach 1.0 V) limits inrush current into bulk capacitance - prevents input rail collapse during system boot. |

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 |
|---|---|---|---|
| MP8859 from Monolithic Power Systems | Single 20 A 4-phase buck (not dual-rail); no integrated DVC pin; requires external sense resistors for current monitoring. | Best suited for single-rail high-current SoC supplies, not independent CPU+DDR dual-rail architectures. | Select only if application consolidates both rails onto one output and accepts higher external component count. |
| TPS65988 from Texas Instruments | USB-C PD controller + dual 10 A bucks; includes USB PD protocol stack and Type-C port management logic. | Targeted at USB-C powered devices requiring port negotiation - adds complexity and cost where USB-C is not needed. | Choose when USB-C power delivery and dual-rail PMIC must be integrated; avoid for pure battery-powered mobile SoC designs. |
Compared with MP8859 and TPS65988, DA9214-XXUP2 uniquely delivers two fully independent, remotely sensed 10 A rails with pin-based DVC and zero external power switches - optimizing footprint, efficiency, and SoC interface simplicity for smartphones and tablets.

FAQ
What is the maximum output current capability of the DA9214-XXUP2?
The DA9214-XXUP2 delivers two independent 10 A output rails - Buck A and Buck B - each capable of up to 10 A continuous current. This is achieved using dual-phase topology per rail with integrated 26 mΩ PMOS and 18 mΩ NMOS power switches in the WL-CSP package. The device sustains full 10 A per rail under 85 °C ambient with proper PCB thermal design and 47 µF output capacitance per phase.
Does the DA9214-XXUP2 support remote voltage sensing?
Yes, the DA9214-XXUP2 implements true remote sensing on both output rails: FBAP/FBAN for Buck A and FBBP/FBBN for Buck B. These differential sense inputs connect directly at the point of load to compensate for PCB trace resistance, ensuring ±1% static output accuracy even under full 10 A load and varying thermal conditions - a key requirement for modern mobile SoCs.
How does Dynamic Voltage Control (DVC) work on the DA9214-XXUP2?
DA9214-XXUP2 supports DVC via two methods: direct register writes over I²C/SPI interface or through a dedicated DVS input pin. When driven by the host processor, the DVS pin adjusts output voltage in real time (e.g., lowering VDD_CPU during low-load states). This feature is hardware-accelerated and requires no firmware intervention, enabling sub-microsecond voltage transitions aligned with CPU DVFS states.
What package options are available for the DA9214-XXUP2?
The DA9214-XXUP2 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 share identical pinout, electrical specifications, and thermal performance (2035 mW total power dissipation for WL-CSP; 1920 mW for VFBGA). The WL-CSP variant provides smallest footprint for ultra-thin mobile designs, while VFBGA offers enhanced manufacturability for standard SMT lines.
Can the DA9214-XXUP2 operate with a 3.3 V input supply?
Yes, the DA9214-XXUP2 operates across a 2.8 V to 5.5 V input range, making 3.3 V fully supported. At 3.3 V input, it maintains full 10 A per rail capability, 3 MHz switching, and ±1% output accuracy. Input ripple rejection exceeds 60 dB at 100 kHz, and internal supervision ensures reliable startup and UVLO protection down to 2.8 V - ideal for regulated intermediate bus or single-cell Li-ion systems.
