DA9132-XXRT2

Overview

The DA9132-XXRT2 is a dual-channel step-down DC/DC converter featuring integrated switching FETs with 3A output per channel. It operates within an input voltage range of 2.8V to 5.5V and provides adjustable output voltages from 0.3V to 1.9V. The device utilizes a 4MHz nominal switching frequency and supports I2C communication for control. Designed for high efficiency exceeding 90%, it reduces thermal management challenges in compact systems.

Feature Summary

• Dual-channel architecture delivering independent power rails with integrated power switches
• High conversion efficiency exceeding 90% to minimize heat generation
• Compact design requiring only two small inductors for optimized board space
• I2C interface enabling dynamic voltage control and programmable GPIO functionality

Applications

• Automotive infotainment and navigation systems
• Advanced Driver Assistance Systems (ADAS)
• Telematics units
• High-performance processing subsystems

Procurement Notes

Verify component authenticity through authorized channels due to restricted supply status. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Ensure compatibility with existing I2C bus configurations and validate thermal performance under specific load conditions before finalizing procurement decisions.

Selection Notes

Select this component when dual low-voltage rails are required with moderate current demands up to 3A per channel. Consider the 24-pin WFQFN package for space-constrained layouts. Evaluate thermal dissipation needs as integrated FETs reduce external component count but require adequate PCB copper area for heat spreading during continuous operation.

Part Context

Part of the Renesas DA913x series, designed as flexible sub-PMIC solutions for automotive and industrial applications. Complements other PMICs by providing dedicated high-current buck regulation. Shares family features like I2C control and soft-start capabilities while offering distinct current ratings compared to higher-capacity variants.

Replacement Considerations

Consider DA9131-XXRT2 for applications requiring higher 5A per channel current capacity. Verify pinout compatibility and inductor specifications when substituting. Ensure output voltage ranges and switching frequencies align with system requirements to maintain stability.
