Product details
Overview
DA9130-08RT2 from Renesas Electronics is a high-performance, dual-phase synchronous buck DC-DC converter PMIC delivering up to 10 A output current at 0.3 V–1.9 V with ±1 % static output voltage accuracy, 4 MHz switching frequency, and integrated power FETs-designed for CPU/GPU/DDR rail regulation in mobile SoC and SIPP modules.
For engineers reviewing the DA9130-08RT2 datasheet, DA9130-08RT2 pinout, DA9130-08RT2 application, or DA9130-08RT2 equivalent, key selection criteria include dual-phase current capability, remote sensing support, I²C-compatible FM+ interface, programmable DVC, and thermal/overcurrent protection without external sensing components.
Technical Context
The DA9130-08RT2 operates as a single-channel, dual-phase buck converter with independent phase control, enabling automatic phase shedding (1↔2 phase) based on load thresholds (1.7 A / 2.25 A). Its fully integrated power stage eliminates external MOSFETs and Schottky diodes, while remote sensing on FB1P/FB1N and FB2P/FB2N ensures ±1 % output accuracy across PCB routing variations.
It supports dynamic voltage control via I²C register writes or dedicated GPIO pins, delivers slope-controlled soft-start to limit inrush current, and integrates cycle-by-cycle current limiting, over-temperature shutdown, and power-good monitoring-all configurable through its 44-register map including BUCK_BUCK1_x and SYS_GPIOx registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2174GQ-Z (Monolithic Power) | 4.5 V–18 V input, 0.6 V–5.5 V output, 8 A max, 500 kHz–2.2 MHz adjustable fSW - lacks remote sensing and DVC GPIO | Targets higher-input industrial systems; not suitable for sub-3 V battery-fed mobile SoCs | Choose MP2174GQ-Z only when input exceeds 5.5 V or board space permits larger inductors/caps |
| TPS62480RHLT (Texas Instruments) | 2.7 V–5.5 V input, 0.6 V–2.5 V output, 8 A max, 2.4 MHz fixed fSW - includes I²C but no auto phase shedding or wettable-flank QFN | Offers lower quiescent current (12 µA in deep sleep) but limited to single-phase operation | Prefer TPS62480RHLT for ultra-low-power always-on subsystems where 10 A peak is not required |

FAQ
What is the maximum output current capability of the DA9130-08RT2?
The DA9130-08RT2 delivers up to 10 A total output current using dual-phase operation (5 A per phase), with automatic phase shedding between 1-phase and 2-phase modes based on load thresholds (1.7 A and 2.25 A). This enables high peak current for CPU/GPU bursts while minimizing light-load quiescent current - a key advantage in battery-powered mobile applications where the DA9130-08RT2 is commonly deployed.
Does the DA9130-08RT2 support remote voltage sensing?
Yes, the DA9130-08RT2 supports true differential remote sensing via dedicated FB1P/FB1N and FB2P/FB2N pins. This feature compensates for PCB trace resistance and ensures ±1 % output voltage accuracy at the load point - critical for maintaining SoC core stability in high-current, space-constrained layouts where the DA9130-08RT2 is used.
What communication interface does the DA9130-08RT2 use?
The DA9130-08RT2 uses an I²C-compatible Fast Mode Plus (FM+) interface operating up to 1 MHz. Its slave address is configurable via the CONF/GPIO0 pin at power-up, allowing up to four unique addresses on the same bus - essential for multi-rail systems using multiple DA9130-08RT2 devices in portable and SIPP module applications.
Is the DA9130-08RT2 qualified for automotive applications?
No, the DA9130-08RT2 is the consumer/industrial variant. The automotive-grade version is the DA9130-A, which is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C ambient) and features enhanced reliability testing. For automotive infotainment or ADAS power rails, the DA9130-A - not the DA9130-08RT2 - must be selected to meet qualification requirements.
What package type and dimensions does the DA9130-08RT2 use?
The DA9130-08RT2 uses a 24-pin FCQFN package with wettable flanks, measuring 3.3 mm × 4.8 mm with 0.5 mm pitch. Its exposed thermal pad and wettable flanks support reliable solder joint inspection and efficient heat dissipation - a design choice aligned with the DA9130-08RT2's role in thermally demanding mobile SoC and SIPP module power delivery.
