Product details
Overview
DA9215-XXUP6 from Renesas Electronics is a multi-phase power management IC integrating a 15 A three-phase buck converter (Buck A) and a 5 A single-phase buck converter (Buck B), optimized for CPU/GPU/DDR rail supply in smartphones and tablets. It operates from 2.8 V–5.5 V input, delivers programmable output voltage from 0.3 V to 1.57 V (±1% static accuracy), and supports remote sensing at point-of-load with 3 MHz switching frequency for low-profile inductor use.
For engineers reviewing the DA9215-XXUP6 datasheet, DA9215-XXUP6 pinout, DA9215-XXUP6 application, or DA9215-XXUP6 equivalent, this page provides verified technical context, phase allocation mapping, real-world load transient performance (±2.5% for Buck A/B under 500 ns/200 ns slew), I²C/SPI-compatible control interface details, and validated alternatives for portable SoC power delivery designs.
Technical Context
The DA9215-XXUP6 implements two independent synchronous buck regulators: Buck A uses phases A1, A2, and B2 (three-phase, 15 A max), while Buck B uses phase B1 (single-phase, 5 A max), per Table 1 and Figure 3. Its digital core supports dynamic voltage control (DVC) via register writes or dedicated DVS pin, enabling adaptive voltage scaling synchronized with processor load states.
It features integrated PMOS/NMOS power switches (RON_PMOS = 26 mΩ WL-CSP, RON_NMOS = 18 mΩ WL-CSP), automatic phase shedding across operating modes, and dual-sense feedback (FBAP/FBAN for Buck A; FBBP/FBBN for Buck B) with remote sensing capability. The 66-ball WL-CSP package (0.4 mm pitch) supports high-density mobile PCB layouts with minimal thermal resistance.
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 - supports DDR4/LPDDR4, GPU cores, and I/O rails. |
| Max Output Current | 15 A (Buck A, 3-phase) + 5 A (Buck B, 1-phase) - enables discrete rail partitioning for heterogeneous SoC domains. |
| Switching Frequency | 3 MHz nominal - allows use of compact 0.22 µH inductors (height ≤1 mm) and reduces output capacitor count. |
| Output Accuracy | ±1% static (VBUCK ≥ 1 V), ±20 mV (VBUCK < 1 V) - ensures stable core voltage under static load for ARM Cortex-A7x/A7xx clusters. |
| Load Transient Response | ±2.5% for Buck A (0–5 A, 500 ns), ±2.5% for Buck B (0–2.5 A, 200 ns) - meets fast DVFS requirements of application processors. |
| Interface Protocol | I²C/SPI-compatible 2-/4-wire bus - supports host-controlled DVC, fault reporting via nIRQ, and configurable I²C address via GPI. |

Pinout & Package
DA9215-XXUP6 is packaged in a 66-ball WL-CSP (0.4 mm pitch), optimized for ultra-thin mobile PCBs. Ball map matches Figure 4 in R16DS0598EJ0361 Rev.03.61.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX_A1, LX_A2, LX_B2 | Switching node (Buck A phases 1/2, Buck A phase B2) | Connects to respective inductor outputs; requires low-inductance layout to minimize EMI and switching loss. |
| LX_B1 | Switching node (Buck B phase 1) | Independent switching path for auxiliary rail; isolated routing prevents coupling into main CPU rail. |
| FBAP / FBAN | Positive/negative sense inputs (Buck A) | Remote sensing pair placed at CPU VDD pin - cancels IR drop in PCB traces for tight regulation. |
| FBBP / FBBN | Positive/negative sense inputs (Buck B) | Enables precision regulation of DDR or GPU I/O rail independent of Buck A loop dynamics. |
| VDD_A1/VDD_A2/VDD_B1/VDD_B2 | Phase supply inputs | Each tied directly to VSYS - ensures consistent gate drive voltage across all integrated FETs. |
| IC_EN | Enable control input | Active-high logic enables full device operation; used for sequencing with system power-on reset. |
| nIRQ | Interrupt output | Open-drain signal asserts on over-temperature, over-current, or UVLO - triggers host firmware fault handling. |
| SDA / SCL / nCS / SO | I²C/SPI interface pins | Supports both 2-wire (I²C) and 4-wire (SPI-like) protocols; nCS polarity and clock phase configurable via OTP. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Switches | Eliminates need for external MOSFETs or Schottky diodes - reduces BOM count and layout area by >30% vs discrete solutions. |
| Dynamic Voltage Control (DVC) | Enables real-time VDD adjustment via register write or dedicated DVS pin - synchronizes supply voltage with CPU frequency scaling for optimal power efficiency. |
| Remote Sensing at Point-of-Load | Compensates for up to 100 mV IR drop across PCB traces - maintains ±1% regulation accuracy at CPU die despite long power delivery paths. |
| Programmable Soft Start | Configurable startup ramp (e.g., BUCKx_UP_CTRL = 100 → 50 µs to 1.0 V) - limits inrush current and prevents input rail collapse during power-up. |
| Automatic Phase Shedding | Reduces active phase count under light load (e.g., Buck A drops from 3→1 phase below 2 A) - cuts quiescent current to 130 µA (IQ_PFM_A3B1) without sacrificing transient response. |
| Configurable I²C Address | GPI0 pin selects between two I²C addresses - allows co-location of multiple DA9215-XXUP6 devices on same bus for multi-rail SoC power trees. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ8633BGLE-Z (Monolithic Power Systems) | Single 16 A 4-phase buck; no secondary buck channel; supports only I²C; lacks remote sensing for secondary rail. | Suitable for CPU-only supply where DDR rail is handled separately; not viable for integrated CPU+GPU+DDR triple-rail architectures. | Select when board space permits larger 5×5 mm QFN and only one high-current rail is required. |
| TPS65981 (Texas Instruments) | USB-C PD controller with integrated 12 A buck; no multi-phase architecture; fixed 0.6–3.6 V output; no DVC or phase shedding. | Targets USB-C power delivery + system rail; not designed for SoC core voltage regulation with fast DVFS. | Choose only for USB-C host port power management - not a functional substitute for DA9215-XXUP6's SoC power delivery role. |
Compared with MPQ8633BGLE-Z and TPS65981, DA9215-XXUP6 uniquely combines dual-buck topology (15 A + 5 A), remote sensing per rail, and DVC-enabled phase shedding - making it the only option among the three qualified for simultaneous CPU/GPU/DDR rail management in space-constrained mobile SoCs.

FAQ
What is the maximum output current capability of the DA9215-XXUP6?
The DA9215-XXUP6 delivers up to 15 A from its three-phase Buck A regulator and 5 A from its single-phase Buck B regulator. These rails operate independently, supporting simultaneous high-current CPU/GPU and lower-current DDR or I/O supply requirements. Each phase is rated for 5 A continuous, with programmable current limits from 4 A to 7 A per phase.
Does the DA9215-XXUP6 support remote voltage sensing for both buck regulators?
Yes, the DA9215-XXUP6 supports true remote sensing for both regulators: FBAP/FBAN pins serve Buck A, and FBBP/FBBN pins serve Buck B. This dual-sense architecture ensures ±1% regulation accuracy at each point-of-load, compensating for PCB trace resistance and enabling precise voltage delivery to CPU cores and memory interfaces.
How does dynamic voltage control (DVC) function on the DA9215-XXUP6?
Dynamic voltage control on the DA9215-XXUP6 operates via either register writes over I²C/SPI or direct assertion of the DVS input pin. It enables real-time adjustment of Buck A or Buck B output voltage in 10 mV steps, synchronized with processor DVFS states - critical for minimizing dynamic power in ARM big.LITTLE and Intel hybrid architectures.
What package options are available for the DA9215-XXUP6, and which is used in the -XXUP6 variant?
The DA9215-XXUP6 uses the 66-ball WL-CSP package with 0.4 mm pitch, as confirmed by Renesas ordering code suffix "UP6". This ultra-compact package measures 3.0 × 3.0 mm and is optimized for thin mobile PCBs. The alternative 66-ball VFBGA (0.5 mm pitch) is designated by suffix "V6", not "UP6".
Can the DA9215-XXUP6 be configured to operate with only one buck regulator enabled?
Yes, the DA9215-XXUP6 supports independent enable/disable control of Buck A and Buck B via dedicated register bits (BUCKA_EN and BUCKB_EN). This allows flexible power sequencing - for example, enabling only Buck B during boot to power DDR before activating Buck A for the application processor - reducing inrush and improving system reliability.
