CS51411ED8G

Overview

The CS51411ED8G is a synchronous step-down DC-DC converter manufactured by onsemi, designed for automotive applications. It operates with an input voltage range of 4.5V to 40V and provides a single adjustable output from 1.27V to 38V at up to 1.5A. The device features a fixed switching frequency of 260kHz and is housed in an 8-pin SOIC package. It supports external bias or synchronization capabilities and functions within a junction temperature range of -40°C to 150°C.

Feature Summary

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

Applications

Automotive power distribution systems
Vehicle infotainment power regulation
ADAS sensor module power supplies

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements as the base model may be non-compliant. Validate package integrity upon receipt. Check datasheet revisions for specific electrical characteristics. Ensure supply chain sources provide traceability documentation.

Selection Notes

Select this component for designs requiring robust automotive-grade synchronous buck conversion. Consider the 260kHz frequency for EMI management. Evaluate thermal performance given the 1.5A continuous current rating. Verify compatibility with external synchronization signals if used in multi-rail systems. Assess input voltage stability against the 40V maximum limit.

Part Context

This part belongs to the CS51411 family of low-voltage buck regulators. It shares architectural similarities with the CS51412 and CS51414 series but differs in switching frequency and specific feature sets. The family targets automotive PMIC applications requiring reliable DC-DC conversion in harsh environments.
