DA9122-E0V72

Overview

The DA9122-E0V72 is a dual-channel synchronous buck converter manufactured by Renesas Electronics. It integrates two independent channels, each capable of delivering up to 5A of output current for a combined total of 10A. The device operates with an input voltage range from 2.5V to 5.5V and provides adjustable output voltages between 300mV and 1.9V. It utilizes a fixed switching frequency of 4MHz and is housed in a compact WLCSP-24 package. The component supports shutdown functionality and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent control over two power rails
• High-efficiency synchronous rectification design for optimized power conversion
• Compact wafer-level chip-scale packaging suitable for space-constrained layouts

Applications

• Powering high-performance mobile processors requiring multiple voltage domains
• Supplying power to memory subsystems in portable computing devices
• Providing regulated voltage rails for system-on-chip (SoC) components

Procurement Notes

Verify the specific suffix against official documentation, as variations exist within the product family. Confirm availability status directly with authorized distributors or the manufacturer due to potential supply constraints. Ensure the selected variant matches the required output configuration and package type for your specific application design.

Selection Notes

Select this component when a dual-rail solution is required for processor core and I/O power domains. Evaluate the thermal performance requirements given the high current density in the WLCSP-24 package. Consider the 4MHz switching frequency for its impact on external inductor size and electromagnetic interference characteristics relative to lower frequency alternatives.

Part Context

This part belongs to the DA912x series of sub-PMICs designed for mobile applications. It complements other variants like the DA9121 by offering a dedicated dual-channel buck topology. The series targets the power management needs of modern handheld devices where efficiency and footprint are critical design parameters.

Replacement Considerations

Check for pin-compatible alternatives within the same Renesas portfolio if supply is limited. Verify that any substitute maintains the 10A total current capability and compatible output voltage ranges.
