DA9132-XXRT1

Overview

The DA9132-XXRT1 is a high-efficiency, dual-channel step-down DC/DC converter manufactured by Renesas Electronics. It integrates switching FETs to deliver 3A output current per channel with an input voltage range of 2.5V to 5.5V and an adjustable output voltage from 0.3V to 1.9V. The device operates at a nominal switching frequency of 4MHz and features an I2C-compatible interface for dynamic control. Packaged in a 24-pin FC-QFN (3.3mm x 4.8mm) with wettable flanks, it supports an operating temperature range of -40°C to +105°C.

Feature Summary

• Dual-channel architecture providing independent 3A current capability per channel
• Integrated switching FETs eliminate the need for external power components
• I2C-compatible interface enables programmable GPIOs and dynamic voltage control
• Advanced safety features include voltage, current, and temperature supervision

Applications

• High-performance mobile processors requiring efficient power delivery
• Automotive infotainment and telematics systems
• Advanced Driver Assistance Systems (ADAS)
• General-purpose low-voltage system power rails

Procurement Notes

Verify the specific suffix configuration against official datasheets before ordering, as OTP finalization may render parts non-cancellable. Confirm package type and lead-free status via manufacturer documentation. Ensure compatibility with I2C bus speeds and check for automotive qualification requirements if deploying in vehicle environments. Cross-reference part numbers carefully to distinguish between industrial and automotive grades.

Selection Notes

Select this component when designing systems requiring dual independent buck converters with integrated power stages. It is suitable for applications needing high efficiency above 90% to minimize thermal management complexity. Consider the 24-pin FC-QFN footprint constraints and verify that the required output voltage falls within the 0.3V to 1.9V range or requires external dividers for higher voltages.

Part Context

This device belongs to the DA9132 series of Sub-PMICs designed for flexible and scalable power solutions. It complements other Renesas power management products by offering a compact, high-current solution for processing cores. The series emphasizes optimized bill-of-materials through integrated inductor requirements and small passive components.

Replacement Considerations

Consult official substitution lists for verified alternatives. The DA9131-A offers similar functionality but with 5A per channel capacity. Verify pinout compatibility and electrical specifications before swapping components in existing designs.
