CS51411GDR8G

Overview

The CS51411GDR8G is a synchronous step-down switching regulator manufactured by onsemi. It operates with an input voltage range of 4.5 V to 40 V and delivers up to 1.5 A of output current. The device supports adjustable output voltages from 1.27 V to 38 V. It features selectable switching frequencies of 260 kHz or 520 kHz, enabling external bias or synchronization capabilities. Packaged in an 8-SOIC surface-mount case, it is designed for automotive applications with an operating junction temperature range of -40°C to +150°C.

Feature Summary

Synchronous buck topology providing efficient step-down conversion
External bias or synchronization capability for system timing control
Automotive-grade reliability with extended high-temperature operation

Applications

Automotive infotainment systems
Vehicle telematics units
ADAS sensor power supplies

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance and lead-free specifications against specific manufacturing lot codes. Validate package marking and pinout alignment with the SOIC-8 standard before integration into production designs.

Selection Notes

Select this component for designs requiring robust automotive power management within a compact footprint. Ensure thermal management strategies accommodate the specified junction temperature limits. Verify that the chosen switching frequency aligns with electromagnetic interference requirements and external synchronization sources.

Part Context

This part belongs to the CS5141x family of low-voltage buck regulators. It shares functional similarities with variants like the CS51412 and CS51413 but differs in specific switching frequency options and feature sets. The family targets automotive electronics requiring reliable DC-DC conversion under harsh environmental conditions.

Replacement Considerations

CS51411GD8G is a tube-packaged equivalent. CS51412GDR8G offers similar functionality with potential frequency variations. Verify electrical parameters and package compatibility when substituting.
