SIC424CD-T1-GE3

Overview

The SIC424CD-T1-GE3 is a microBUCK integrated buck regulator featuring an integrated 5 V LDO. It delivers 6 A continuous output current with efficiency exceeding 95%. The device includes an integrated bootstrap switch and supports input voltages from 2.5 V to 24 V. Output voltage ranges from 0.75 V to 5.5 V. It utilizes a 44MLP-28 package.

Feature Summary

• Integrates a high-efficiency synchronous buck converter with an independent 5 V linear regulator.
• Includes an internal bootstrap switch to simplify external component requirements.
• Features bypass logic for the integrated LDO to optimize performance under varying load conditions.

Applications

• Point-of-load regulation in industrial equipment
• Power management for embedded computing systems
• Telecommunications infrastructure power distribution

Procurement Notes

Verify the specific suffix and tape-and-reel configuration against the manufacturer's latest datasheet before ordering. Confirm that the 44MLP-28 footprint matches your PCB design constraints. Ensure thermal management strategies align with the 6 A continuous current capability and junction temperature limits specified in the official documentation.

Selection Notes

Select this component when a compact solution combining a high-current buck converter with a low-noise LDO is required. The integrated bootstrap switch reduces bill of materials count. Verify that the input voltage range of 2.5 V to 24 V covers your system's supply variations. Consider the thermal dissipation characteristics of the 44MLP-28 package for your enclosure design.
