Renesas DA9130-08RT2-A

Overview

DA9130-08RT2-A from Renesas Electronics is a high-performance, dual-phase synchronous buck DC-DC converter PMIC delivering up to 10 A at 0.3–1.9 V output from a 2.8–5.5 V input, featuring 4 MHz switching frequency, ±1 % static output voltage accuracy, and integrated FETs for CPU/GPU/DDR power rails in SIPP modules and portable SoC systems.

For engineers reviewing the DA9130-08RT2-A datasheet, DA9130-08RT2-A pinout, DA9130-08RT2-A application, or DA9130-08RT2-A equivalent, key selection considerations include dual-phase current capability, I²C-compatible FM+ interface with configurable GPIOs, remote sensing for precision regulation, thermal and over-current protection, and 24-pin FCQFN wettable-flank package compatibility with high-density mobile PCB layouts.

Technical Context

The DA9130-08RT2-A implements a single-channel, dual-phase buck topology with cycle-by-cycle current limiting and automatic phase shedding (1↔2 phase) triggered at 1.7 A / 2.25 A thresholds. It supports both PWM and PFM modes, achieving 85 % efficiency at 5–80 % load and 83 % at light load (10 mA), with programmable soft-start and dynamic voltage control (DVC) via register write or dedicated input pin.

Its architecture integrates high-side and low-side MOSFETs (RON_PMOS = 17–37 mΩ, RON_NMOS = 6–16 mΩ per phase), eliminating external FETs or diodes. Remote sensing on FB1P/FB1N and FB2P/FB2N enables accurate load-point regulation across varied PCB routing, while thermal protection activates at TJ_WARN (125 °C) and TCRIT (150 °C) with no external components required.

FAQ

What is the maximum output current capability of the DA9130-08RT2-A?

The DA9130-08RT2-A delivers up to 10 A total output current in dual-phase operation, with 5 A per phase. It supports automatic phase shedding-operating in 2-phase mode above 2.25 A and switching to 1-phase below 1.7 A-to maintain high efficiency across light and heavy loads. This capability is confirmed in Table 8 of the Renesas datasheet R16DO0058EJ0301 Rev.03.01, and applies directly to the DA9130-08RT2-A variant.

Does the DA9130-08RT2-A support dynamic voltage control (DVC) without an I²C host?

Yes, the DA9130-08RT2-A supports DVC via a dedicated GPIO pin (e.g., CONF/GPIO0 or GPIO1) configured as a DVC input, allowing direct analog or digital level shifting to adjust output voltage without I²C communication. This is documented in Section 5.1.3 ("Output Voltage Selection") and Table 17 ("GPIO Function Configuration") of the datasheet. The DA9130-08RT2-A implements this feature natively and does not require firmware or external controllers for basic DVC operation.

What package type and dimensions does the DA9130-08RT2-A use?

The DA9130-08RT2-A uses a 24-pin FCQFN package measuring 3.3 mm × 4.8 mm with 0.4 mm pitch and wettable flanks, as specified in Section 9 ("Package Outline Drawings") and Figure 14 of the official datasheet. This package is thermally optimized for high-current operation and supports automated optical inspection. The DA9130-08RT2-A's footprint matches Renesas' standard FCQFN layout (Figure 15), and its thermal resistance (θJA = 21.21 °C/W) is validated on JEDEC 2S2P boards.

Is remote sensing supported on both output phases of the DA9130-08RT2-A?

Yes, the DA9130-08RT2-A provides independent remote sensing for both phases: FB1P/FB1N for Phase 1 and FB2P/FB2N for Phase 2. These differential inputs enable Kelvin connection to the load, compensating for PCB trace resistance and maintaining ±1 % output accuracy under varying current conditions. This dual-sense capability is explicitly defined in Table 1 ("Pin Description") and Section 5.1.3 of the DA9130-08RT2-A datasheet.

What protection features are integrated into the DA9130-08RT2-A?

The DA9130-08RT2-A integrates cycle-by-cycle over-current protection, thermal shutdown at TJ_WARN (125 °C) and TCRIT (150 °C), and power-good monitoring with programmable hysteresis. No external sensors or components are required-these functions are implemented entirely within the IC. Protection behavior is detailed in Sections 3.5 ("Buck Characteristics"), 5.1.5 ("Current Limit"), and 5.1.6 ("Thermal Protection") of the DA9130-08RT2-A datasheet R16DO0058EJ0301 Rev.03.01.
