Product details

Overview

DA9130-21RT1 from Renesas Electronics is a high-performance, dual-phase synchronous buck PMIC delivering up to 10 A at 0.3 V–1.9 V output from a 2.8 V–5.5 V input, featuring integrated FETs, 4 MHz switching, ±1 % static output voltage accuracy, and remote sensing for CPU/GPU/DDR power rails in SIPP modules and portable SoC systems.

For engineers reviewing the DA9130-21RT1 datasheet, DA9130-21RT1 pinout, DA9130-21RT1 application, or DA9130-21RT1 equivalent, this page provides verified technical context, validated pin functions, confirmed dual-phase buck specifications, real-world application mappings, and two rigorously cross-checked alternative parts for mobile and industrial power delivery designs.

Technical Context

The DA9130-21RT1 operates as a single-channel, dual-phase buck converter with independent phase control, enabling automatic phase shedding (1↔2 phase) based on load current thresholds (1.7 A / 2.25 A). It uses fully integrated high-side and low-side MOSFETs (RON_PMOS = 17–37 mΩ, RON_NMOS = 6–16 mΩ per phase) and supports both PWM and PFM modes for efficiency optimization across load ranges.

It implements dynamic voltage control (DVC) via I²C (FM+ compatible) or dedicated GPIO pins, programmable soft-start, cycle-by-cycle current limiting, and integrated thermal protection (TJ_WARN and TCRIT thresholds). Remote sensing on FB1P/FB1N and FB2P/FB2N ensures ±1 % static accuracy without PCB routing compromises.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-phase buck PMIC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MP2965A from Monolithic Power Systems	4-phase capable (vs. DA9130-21RT1's dual-phase), higher 16 A rating, but larger 5 mm × 5 mm QFN and no wettable flanks.	Targeted at server-grade SoCs; less suitable for space-constrained portable SIPP modules.	Choose MP2965A only when >10 A or 4-phase redundancy is required; DA9130-21RT1 offers better footprint and thermal reliability in mobile form factors.
TPS65988 from Texas Instruments	USB-C PD controller + dual-buck combo; buck section rated 6 A (not 10 A), lacks remote sensing and phase-shedding hysteresis tuning.	Optimized for USB-C docking stations-not for standalone high-current SoC core rails.	Select TPS65988 only if USB-C PD negotiation and integrated Type-C control are mandatory; DA9130-21RT1 delivers superior current density and precision for dedicated processor rails.

Compared with MP2965A and TPS65988, DA9130-21RT1 uniquely balances 10 A capability, 4 MHz switching, remote sensing accuracy, and 3.3 mm × 4.8 mm wettable-flank packaging-making it the optimal choice for thermally demanding, space-limited mobile and industrial SoC power delivery where layout simplicity and long-term reliability are critical.

FAQ

What is the maximum output current supported by the DA9130-21RT1?

The DA9130-21RT1 delivers up to 10 A total output current in 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 is confirmed in Table 8 of the R16DO0058EJ0301 datasheet under IMAX and ITHR specifications. The DA9130-21RT1 maintains this rating across −40 °C to +105 °C ambient with appropriate PCB thermal design.

Does the DA9130-21RT1 support remote voltage sensing?

Yes, the DA9130-21RT1 supports true differential remote sensing via dedicated FB1P/FB1N and FB2P/FB2N pins, enabling Kelvin connection directly at the load point. This guarantees ±1 % static output voltage accuracy regardless of PCB trace resistance or routing topology, as specified in Table 8 (VOUT_ACC) and detailed in Section 5.1.3 of the datasheet. The DA9130-21RT1 uses this feature to maintain regulation integrity in dense, multi-layer layouts common in SIPP modules.

What package type and dimensions does the DA9130-21RT1 use?

The DA9130-21RT1 is packaged in a 24-pin FCQFN with wettable flanks, measuring 3.3 mm × 4.8 mm (nominal) and 0.5 mm height. Its pinout and mechanical drawing are shown in Figure 4 and Figure 14 of the R16DO0058EJ0301 datasheet. The wettable flanks enable reliable solder joint inspection via AOI, and the compact footprint supports high-density portable designs-key for DA9130-21RT1 deployment in space-constrained SoC and DDR modules.

Can the DA9130-21RT1 operate in both PWM and PFM modes?

Yes, the DA9130-21RT1 supports both PWM and PFM operating modes. In PWM mode, it achieves >85 % efficiency from 5 % to 80 % load with 4 MHz switching; in PFM mode, quiescent current drops to 164 µA (no switching) for light-load efficiency, as documented in Table 8 (ηPFM and IQ_PFM_2PH). Mode selection is automatic or configurable via registers, and the DA9130-21RT1 transitions seamlessly between them to optimize power conversion across dynamic workloads.

Is the DA9130-21RT1 qualified for automotive applications?

The DA9130-21RT1 itself is not automotive-qualified; however, Renesas offers the pin-compatible DA9130-A variant, which is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C) and listed in Table 54 of the datasheet. The DA9130-21RT1 shares identical electrical specs and pinout but is intended for industrial and consumer portable applications. For automotive designs requiring qualification, the DA9130-A must be selected-DA9130-21RT1 should not be substituted without revalidation.
