CS51414EDR8G

Overview

The CS51414EDR8G is a synchronous buck switching regulator IC manufactured by onsemi. It provides an adjustable output voltage ranging from 1.27V to 38V with a maximum output current of 1.5A. The device operates with an input voltage range of 4.5V to 40V and features a fixed switching frequency of 520kHz. Designed for surface-mount installation, it utilizes an 8-SOIC package (0.154 inch width). The component supports a junction temperature operating range of -40°C to 150°C and includes positive output configuration.

Feature Summary

Synchronous rectification topology for improved efficiency
Adjustable output voltage capability within specified limits
Integrated high-side and low-side power switches

Applications

Point-of-load regulation in industrial systems
Power supply stages for embedded computing platforms
Battery-powered equipment requiring efficient DC-DC conversion

Procurement Notes

Verify the specific suffix 'EDR8G' against official onsemi documentation to confirm pinout compatibility and electrical specifications relative to other variants in the CS51414 series. Confirm RoHS compliance status and lead-free marking requirements prior to integration into manufacturing processes.

Selection Notes

Select this component when a synchronous buck converter is required for high-efficiency applications. Ensure the design accommodates the 520kHz switching frequency and the 4.5V to 40V input range. Verify that the thermal management strategy supports the 150°C maximum junction temperature rating under expected load conditions.

Part Context

This part belongs to the CS51414 family of synchronous buck regulators. It serves as a direct parameter-equivalent replacement for the discontinued CS51414GDR8G model. Both devices share identical functional characteristics and pin configurations, allowing for drop-in upgrades in existing designs.

Replacement Considerations

The CS51414EDR8G is the confirmed parameter-equivalent substitute for the obsolete CS51414GDR8G. No external components or layout changes are typically required for migration between these two specific part numbers.
