CS51413EDR8

Overview

The CS51413EDR8 is a 1.5 A buck regulator IC from onsemi, operating at a fixed frequency of 260 kHz. It utilizes V2 control architecture for stable regulation. The device supports an input voltage range of 4.5 V to 40 V and provides an adjustable output voltage between 1.27 V and 38 V. Packaged in an 8-SOIC case, it is designed for surface-mount installation with a wide operating temperature range.

Feature Summary

• Integrates V2 control architecture for robust transient response
• Supports high input voltage up to 40 V
• Delivers continuous 1.5 A output current
• Features adjustable output voltage capability

Applications

• Industrial power supply systems
• Telecommunications equipment
• Point-of-load regulation modules

Procurement Notes

Verify component authenticity through authorized distribution channels due to the availability of counterfeits in the market. Confirm RoHS compliance status and specific package markings against official datasheets before integration. Check for obsolescence notices as this part may be subject to discontinuation or lifecycle changes.

Selection Notes

Select this component when a synchronous buck converter is not required but high efficiency is needed. Ensure the application operates within the 4.5 V to 40 V input range. Consider thermal management requirements for the SOIC-8 package under full load conditions. Verify that the 260 kHz switching frequency aligns with EMI constraints.

Part Context

This part belongs to the CS5141X family of 1.5 A buck regulators. It shares architectural similarities with variants like the CS51414, differing primarily in switching frequency specifications. The family targets cost-sensitive applications requiring reliable DC-DC conversion without complex digital interfaces.

Replacement Considerations

CS51414EDR8G is listed as a parameter-equivalent substitute.
