DA9092-XX

Overview

The DA9092-XX is a power management integrated circuit (PMIC) designed for mobile applications. It integrates multiple DC/DC converters and linear regulators to provide efficient power distribution. The device supports various output configurations to meet the dynamic power requirements of system-on-chip (SoC) components. Key electrical characteristics include input voltage ranges compatible with single-cell lithium-ion batteries and programmable output voltages for precise regulation. Integrated features typically encompass protection mechanisms such as over-current and thermal shutdown to ensure reliable operation in portable electronic devices.

Feature Summary

• Integrates high-efficiency synchronous buck converters for core voltage generation
• Includes low-noise linear regulators for sensitive analog and RF circuits
• Supports dynamic voltage scaling to optimize power consumption based on load conditions
• Features comprehensive protection schemes including over-temperature and short-circuit protection

Applications

• Smartphones and mobile phones
• Tablets and handheld computing devices
• Portable media players
• Internet of Things (IoT) wearables

Procurement Notes

Verify the specific suffix variant (e.g., -XX) against the official Renesas datasheet to confirm pinout compatibility and functional configuration. Ensure that the selected package type matches the PCB footprint requirements. Confirm RoHS compliance status and lead-free soldering specifications for assembly processes. Cross-reference the ordering code with the manufacturer's current product availability list to avoid obsolete part numbers.

Selection Notes

Evaluate the total number of required power rails against the internal converter count to minimize component count. Consider the quiescent current specifications for battery-operated applications requiring extended standby times. Assess the thermal performance capabilities relative to the expected ambient operating conditions. Verify interface compatibility, such as I2C or SPI, for system control and monitoring integration.

Part Context

The DA9092 series belongs to Renesas' portfolio of power management solutions for mobile electronics. It complements other PMICs by offering a balance of integration density and flexibility. This family targets applications needing compact footprints and high efficiency. It is often paired with application processors and memory subsystems in consumer electronics designs.

Replacement Considerations

Check for direct cross-references in the Renesas product selection guide. Verify if newer revisions offer improved efficiency or updated packaging options. Ensure that any substitute part maintains identical pin-to-pin compatibility and electrical parameters.
