CS51411EDR8G

Overview

The CS51411EDR8G is a synchronous buck switching voltage regulator manufactured by onsemi. It delivers a continuous output current of 1.5 A with an adjustable output voltage range from 1.27 V to 38 V. The device operates within an input voltage window of 4.5 V to 40 V and supports switching frequencies of 260 kHz or 520 kHz. It features external bias or synchronization capabilities and is housed in an 8-SOIC package. The component is rated for a junction temperature range of -40°C to +150°C.

Feature Summary

Synchronous rectification architecture for high efficiency
Adjustable output voltage capability across a wide range
Supports external clock synchronization for noise management

Applications

Point-of-load regulation in industrial systems
Power supply stages for embedded computing platforms
Bias voltage generation for communication equipment

Procurement Notes

Verify the RoHS compliance status carefully, as legacy variants may differ. Confirm the specific switching frequency configuration (260 kHz vs 520 kHz) required for the design. Ensure the SOIC-8 package dimensions match the PCB footprint. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing the bill of materials.

Selection Notes

Select this component when a robust 1.5 A synchronous buck solution is needed with flexible input voltage support up to 40 V. The external synchronization feature makes it suitable for systems requiring precise timing alignment. Consider the thermal performance of the SOIC-8 package under maximum load conditions. Verify that the adjustable output range meets the specific rail requirements of the target application.

Part Context

This part belongs to the CS5141x family of low-voltage buck regulators from onsemi. The series includes variants with different switching frequencies and package options. These devices are designed for applications requiring efficient power conversion in compact form factors. The family shares common control logic but varies in specific electrical parameters and thermal handling capabilities.
