Product details
Overview
DA9213-XXUP6 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 3 MHz switching frequency enabling use of 1 mm-height inductors.
For engineers reviewing the DA9213-XXUP6 datasheet, DA9213-XXUP6 pinout, DA9213-XXUP6 application, or DA9213-XXUP6 equivalent, key selection considerations include its 4-phase architecture, remote sensing capability at point-of-load, I²C/SPI-compatible interface with configurable address via GPI, programmable soft start, and integrated over-temperature/over-current protection.
Technical Context
The DA9213-XXUP6 implements a fully integrated 4-phase synchronous buck topology with automatic phase shedding across light-to-heavy load conditions. Its digital core supports dynamic voltage control (DVC) via register writes or dedicated DVS pin, enabling real-time supply adaptation to processor load states without external components.
It uses internal power switches (PMOS/NMOS) with RON ≤ 27 mΩ (PMOS) and ≤ 19 mΩ (NMOS) per phase, supports remote sensing on FBAP/FBAN for Buck A, and includes dedicated VDDIO rail supervision and VDDIO under-voltage lockout for system-level reliability.

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 |
|---|---|---|---|
| MP8859GQ-Z | 4-phase, 20 A, 2.7–16 V input, no remote sensing, fixed 500 kHz–2.2 MHz frequency | Targets higher-input industrial/portable systems; lacks DVC and PoL sensing | Choose MP8859GQ-Z only if input exceeds 5.5 V or remote sensing is unnecessary |
| TPS549D22RUKR | 4-phase, 20 A, 3–16 V input, PMBus interface, no integrated DVC pin, requires external compensation | Designed for server/client computing; supports telemetry but adds complexity | Choose TPS549D22RUKR when PMBus telemetry and multi-rail coordination are required over simplicity and mobile optimization |
Compared with MP8859GQ-Z and TPS549D22RUKR, the DA9213-XXUP6 delivers superior mobile-specific integration - including native DVC support, remote sensing, and ultra-low quiescent current in PFM - making it optimal for space- and battery-constrained portable SoC power delivery.

FAQ
What is the maximum output current supported by the DA9213-XXUP6?
The DA9213-XXUP6 supports up to 20 A total output current using its four-phase architecture, with each phase rated for 5 A continuous operation. This is confirmed in the datasheet's front-page summary and Table 6 (IO_MAX = 5000 mA per phase). The device sustains this rating under recommended operating conditions (TA ≤ 85 °C, proper thermal layout).
Does the DA9213-XXUP6 support remote sensing, and how is it implemented?
Yes, the DA9213-XXUP6 supports remote sensing for Buck A via dedicated FBAP and FBAN pins, enabling Kelvin connection directly at the point-of-load. This compensates for PCB trace resistance and ensures ±1% output voltage accuracy regardless of layout-induced IR drop - a feature explicitly documented in the datasheet Section 5.2.1 and Figure 1.
What communication interfaces does the DA9213-XXUP6 support, and are they pin-compatible?
The DA9213-XXUP6 supports both I²C (2-wire) and SPI (4-wire) interfaces using shared pins: SDA/SCL for I²C and SDA/SCL/nCS/SO for SPI. Interface mode is auto-detected at power-up based on nCS behavior. No hardware modification is needed to switch protocols - the same DA9213-XXUP6 pinout supports both.
Can the DA9213-XXUP6 be used for DDR memory rail supply?
Yes, the DA9213-XXUP6 is suitable for DDR memory rails (e.g., LPDDR4 VDDQ/VDD2), as confirmed by its 0.3–1.57 V output range, ±1% static accuracy, and fast 10 A/µs transient response. The datasheet explicitly lists "DDR memory rails" in the Applications section and demonstrates PoL regulation critical for memory timing integrity.
What package options are available for the DA9213-XXUP6, and are they interchangeable?
The DA9213-XXUP6 is offered in two package variants: 66-ball WL-CSP (0.4 mm pitch) and 66-ball VFBGA (0.5 mm pitch). Both share identical pinouts (Figures 4 and 5 of datasheet) and electrical specifications, but require separate PCB footprints due to differing ball pitch and mechanical dimensions.
