CS51411GD8G

Overview

The CS51411GD8G is a synchronous step-down DC-DC converter manufactured by onsemi, designed for automotive applications. It operates within an input voltage range of 4.5V to 40V and delivers a single adjustable output up to 38V with a maximum current of 1.5A. The device supports switching frequencies of 260 kHz and 520 kHz, featuring external bias or synchronization capabilities. Packaged in an 8-pin SOIC (0.154" width), it functions across a junction temperature range of -40°C to 150°C.

Feature Summary

• Synchronous buck topology for high efficiency
• External bias or synchronization capability
• Automotive qualified reliability

Applications

• Automotive power distribution systems
• Low voltage DC-DC conversion for electronic control units
• Point-of-load regulation in vehicle networks

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and marking specifications against official datasheets. Check for RoHS compliance variations as historical data indicates non-compliance for this specific revision. Ensure substitution parts meet identical electrical and thermal requirements.

Selection Notes

Select this component for automotive environments requiring robust input voltage handling up to 40V. Consider the 8-SOIC package for surface mount assembly constraints. Evaluate thermal performance at 150°C junction limits. Verify frequency selection matches system synchronization needs between 260 kHz and 520 kHz options.

Part Context

Part of the CS5141x family of low voltage buck regulators from onsemi. Designed specifically for automotive electronics, offering integrated switches and control logic. Shares functional similarities with CS51412 and CS51414 variants, differing primarily in packaging or minor electrical characteristics within the same product line.

Replacement Considerations

CS51411GD8G is obsolete. No direct public substitute part numbers are confirmed in available documentation.
