Product details
Overview
DA9130-XXRT1-A from Renesas Electronics is a high-performance, AEC-Q100 Grade 2 qualified dual-phase buck DC-DC converter PMIC designed for automotive CPU/GPU/DDR power rails. It delivers up to 10 A total output current across two phases, supports 0.3 V–1.9 V programmable output voltage with ±1 % static accuracy, operates from 2.8 V–5.5 V input, and integrates fully synchronous FETs in a 24-pin FCQFN (3.3 mm × 4.8 mm) package with wettable flanks.
For engineers reviewing the DA9130-XXRT1-A datasheet, DA9130-XXRT1-A pinout, DA9130-XXRT1-A application, or DA9130-XXRT1-A equivalent, key selection considerations include its 4 MHz switching frequency, remote sensing capability for precision regulation, I2C-compatible FM+ interface for dynamic voltage control (DVC), integrated thermal/over-current protection, and qualification for vehicle infotainment, ADAS, and telematics systems.
Technical Context
The DA9130-XXRT1-A implements a single-channel, dual-phase synchronous buck architecture with interleaved operation to reduce input/output ripple and improve transient response. Each phase uses an integrated high-side and low-side MOSFET pair, eliminating external FETs or Schottky diodes, and supports independent current limiting and soft-start control.
It features a fully programmable I2C-compatible FM+ interface (up to 1 MHz), configurable GPIOs (CONF/GPIO0, GPIO1, GPIO2, SCL/GPIO3, SDA/GPIO4), remote sensing via FB1P/FB1N and FB2P/FB2N, and hardware-based fault handling including cycle-by-cycle current limiting and thermal shutdown at 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V - compatible with automotive 3.3 V and 5 V bias rails without external LDO pre-regulation. |
| Output Voltage Range | 0.3 V to 1.9 V in 10 mV steps - enables precise core voltage scaling for SoCs and GPUs under DVC control. |
| Max Output Current | 10 A total (5 A per phase) - supports high-current digital loads while maintaining thermal stability in compact layouts. |
| Switching Frequency | 4 MHz nominal - allows use of ultra-small 220 nH inductors and reduces solution footprint to 218 mm². |
| Output Voltage Accuracy | ±1 % (static, VOUT ≥ 1 V) - ensures stable rail regulation under line/load variations without external trimming. |
| Protection Features | Integrated over-temperature shutdown (TJ = 150 °C), cycle-by-cycle current limiting, and power-good monitoring - eliminates need for discrete supervision ICs. |
| Interface | I2C-compatible FM+ (up to 1 MHz) with configurable slave address - enables multi-device coordination and register-level DVC updates. |
| Operating Temperature | −40 °C to +105 °C ambient - meets AEC-Q100 Grade 2 requirements for under-hood and cabin electronics. |
