DA9220-70V72

Overview

The DA9220-70V72 is a dual-output synchronous buck regulator manufactured by Renesas Electronics. It integrates two independent channels, each capable of delivering up to 3 A of output current. The device operates with an input voltage range from 2.5 V to 5.5 V and provides adjustable output voltages between 300 mV and 1.9 V. It utilizes a fixed switching frequency of 4 MHz for efficient power conversion. The component supports operation within a temperature range of -40°C to +85°C and is housed in a WLCSP-24 package.

Feature Summary

• Integrates two independent high-efficiency synchronous buck converters on a single chip
• Supports programmable output voltage adjustment across a wide low-voltage range
• Features integrated shutdown control for power management flexibility

Applications

• Portable consumer electronics requiring compact dual-rail power solutions
• Embedded systems utilizing low-voltage logic families
• Battery-powered devices needing efficient step-down regulation

Procurement Notes

Verify the specific suffix '70V72' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the required operating temperature range aligns with the industrial limits defined in the product documentation. Cross-reference the WLCSP-24 package dimensions with PCB layout guidelines prior to implementation.

Selection Notes

Select this component when a system requires two isolated power rails derived from a single 2.5 V to 5.5 V source. It is suitable for applications prioritizing space efficiency due to its WLCSP-24 footprint. Consider the 4 MHz switching frequency regarding electromagnetic interference constraints and filter component sizing requirements.

Part Context

This part belongs to the DA9220 series of dual-output buck regulators designed for portable applications. It represents a specialized power management solution offering integrated current sensing and protection features within a minimal form factor, distinct from single-channel or higher-current PMIC alternatives.

Replacement Considerations

Consult the manufacturer's cross-reference list for verified substitutes. Ensure any alternative maintains identical output current capabilities, input voltage ranges, and package dimensions to guarantee mechanical and electrical compatibility.
