Product details
Overview
DA9132-XXRT2 from Renesas Electronics is a dual-channel, fully integrated buck DC-DC power management IC (PMIC) designed for CPU/GPU and DDR memory rail regulation in mobile, portable, and automotive-grade SIPP modules. It delivers up to 3 A per channel across 0.3 V–1.9 V output range from a 2.8 V–5.5 V input, features 4 MHz switching frequency, ±1% static output voltage accuracy, and remote sensing for precision regulation.
For engineers reviewing the DA9132-XXRT2 datasheet, DA9132-XXRT2 pinout, DA9132-XXRT2 application, or DA9132-XXRT2 equivalent, key selection criteria include dual-buck integration with no external FETs, I2C-compatible FM+ interface, programmable soft-start, dynamic voltage control (DVC), and AEC-Q100 Grade 2 qualification support via variant DA9132-A.
Technical Context
The DA9132-XXRT2 implements two independent, synchronous single-phase buck converters with integrated high- and low-side MOSFETs, operating at 4 MHz nominal frequency in PWM or auto mode. Each channel supports remote differential feedback (FB1P/FB1N, FB2P/FB2N) and cycle-by-cycle current limiting for robust over-current protection.
Its digital control core includes an I2C-compatible FM+ interface (up to 1 MHz), configurable GPIOs (GPIO0–GPIO4), interrupt reporting (nIRQ), and register-mapped DVC enabling real-time voltage scaling based on processor load-critical for SoC/FPGA power efficiency in battery-constrained systems.

FAQ
What is the input voltage range supported by the DA9132-XXRT2?
The DA9132-XXRT2 supports an input voltage range of 2.8 V to 5.5 V, enabling direct compatibility with single-cell Li-ion batteries, USB Type-C power delivery sources, and standard 3.3 V or 5 V system rails. This range allows the DA9132-XXRT2 to operate without intermediate pre-regulation stages in most portable and automotive subsystems.
Does the DA9132-XXRT2 support dynamic voltage scaling (DVS) or dynamic voltage control (DVC)?
Yes, the DA9132-XXRT2 implements Dynamic Voltage Control (DVC) that adjusts output voltage in real time based on processor load. This can be triggered either via I2C register writes or through a dedicated programmable GPIO pin. The DA9132-XXRT2 uses this feature to reduce power consumption during low-activity CPU/GPU states - a key efficiency enabler in mobile and embedded SoC designs.
What package type and pin count does the DA9132-XXRT2 use?
The DA9132-XXRT2 is packaged in a 24-pin FCQFN (Fine Pitch Chip-scale Quad Flat No-lead) with dimensions of 3.3 mm × 4.8 mm and 0.4 mm pitch. It features wettable flanks for automated optical inspection and includes an exposed thermal pad connected to PGND for efficient heat dissipation - essential for sustained 3 A per channel operation.
Is remote sensing supported on both output channels of the DA9132-XXRT2?
Yes, the DA9132-XXRT2 provides full differential remote sensing on both buck channels via dedicated FB1P/FB1N and FB2P/FB2N pins. This architecture maintains ±1 % output voltage accuracy despite PCB trace resistance, enabling reliable regulation even with long or narrow power distribution paths - a critical capability for high-current SoC and DDR memory applications.
What protection features are integrated into the DA9132-XXRT2?
The DA9132-XXRT2 integrates over-temperature protection (OTP), cycle-by-cycle over-current protection (OCP), and undervoltage lockout (UVLO) - all implemented on-die without external components. These protections respond autonomously and are reported via the I2C interface or nIRQ pin, allowing the host system to take corrective action. The DA9132-XXRT2's integrated supervision eliminates the need for discrete monitoring ICs in space- and cost-sensitive designs.
