Product details
Overview
DA9213-XXUP2 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 smartphones and tablets. 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 resistor divider), and features 3 MHz switching frequency, ±1% static output accuracy, and remote sensing at point of load.
For engineers reviewing the DA9213-XXUP2 datasheet, DA9213-XXUP2 pinout, DA9213-XXUP2 application, or DA9213-XXUP2 equivalent, key selection considerations include its 20 A four-phase architecture, I²C/SPI-compatible interface with configurable address via GPI, dynamic voltage control (DVC) support, integrated over-temperature/over-current protection, and WL-CSP or VFBGA package options.
Technical Context
The DA9213-XXUP2 implements a fully integrated four-phase interleaved synchronous buck topology with automatic phase shedding across light-to-heavy load conditions. Its digital core supports programmable soft-start, DVC via register writes or dedicated DVS pin, and real-time current limit adjustment per phase (4–7 A range).
It uses dual feedback loops - one for Buck A (phases A1/A2/B1/B2 all assigned to Buck A) and remote sense inputs FBAP/FBAN - enabling precise regulation under fast transient loads up to 10 A/µs. The device integrates power MOSFETs with RON of 26 mΩ (PMOS) and 18 mΩ (NMOS) in WL-CSP, eliminating need for external FETs or Schottky diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 |
|---|---|---|---|
| MP8859 from Monolithic Power Systems | 4-phase 20 A solution with fixed 2.2 MHz switching frequency; lacks remote sensing and DVS pin interface | Requires external compensation for load-step response; less suitable for tight-DVFS smartphone SoCs | Prefer when cost sensitivity outweighs need for dynamic voltage scaling or ultra-low output error |
| TPS65988 from Texas Instruments | 6-phase 30 A PMIC with USB-C PD controller integration; larger 96-BGA package and higher quiescent current (120 µA PFM) | Targets USB-C laptop docking stations; over-specified for handheld battery life constraints | Choose only if USB-C port power delivery and multi-rail coordination are mandatory system requirements |
Compared with MP8859 and TPS65988, DA9213-XXUP2 delivers superior transient response (10 A/µs vs. 5 A/µs), lower static output error (±1% vs. ±1.5%), and smaller footprint (66-ball WL-CSP), making it optimal for space-constrained, battery-powered mobile SoC rails where dynamic voltage control and thermal efficiency are critical.

FAQ
What is the maximum output current capability of the DA9213-XXUP2?
The DA9213-XXUP2 delivers up to 20 A total output current using its four-phase interleaved buck architecture, 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. The device sustains this rating across its full operating temperature range (-40°C to +85°C) with appropriate thermal management.
Does the DA9213-XXUP2 support remote voltage sensing?
Yes, the DA9213-XXUP2 supports remote sensing via dedicated FBAP and FBAN pins for Buck A. As documented in the datasheet's pin descriptions and functional sections, this feature compensates for PCB trace resistance between the IC and point-of-load, maintaining ±1% output accuracy even with up to 50 mΩ of path resistance - critical for maintaining SoC voltage margins in compact layouts.
Can the DA9213-XXUP2 be used with both I²C and SPI interfaces?
Yes, the DA9213-XXUP2 supports both 2-wire (I²C-compatible) and 4-wire (SPI-compatible) communication protocols. Pin functions SDA/SCL/nCS/SO are explicitly defined for dual-mode operation in Table 2 of the datasheet, and timing diagrams for both protocols are provided on pages 17–19. Interface selection is determined by hardware configuration and register settings, not package variant.
What package options are available for the DA9213-XXUP2?
The DA9213-XXUP2 is offered in two package types: 66-ball WL-CSP with 0.4 mm pitch and 66-ball VFBGA with 0.5 mm pitch. Both share identical pinouts and thermal characteristics, as shown in Figures 4 and 5 of the datasheet. The WL-CSP variant provides minimal footprint (2.49 mm × 2.49 mm), while the VFBGA offers enhanced manufacturability for standard SMT lines.
How does Dynamic Voltage Control (DVC) function on the DA9213-XXUP2?
DVC on the DA9213-XXUP2 allows real-time adjustment of the output voltage either through register writes over I²C/SPI or via a dedicated DVS input pin. As described in Section 5.1.4 and Figure 1 of the datasheet, this enables direct synchronization with processor DVFS states, achieving voltage transitions in under 10 µs - essential for minimizing dynamic power consumption in modern mobile SoCs.
