CS51412EDR8

Overview

The CS51412EDR8 is a synchronous step-down switching regulator manufactured by onsemi. It operates with an input voltage range of 4.5V to 40V and provides a single adjustable output from 1.27V up to 38V. The device delivers a continuous output current of 1.5A at a fixed switching frequency of 260kHz. Packaged in an 8-SOIC surface-mount format, it supports automotive applications with an operating junction temperature range of -40°C to 150°C.

Feature Summary

• Synchronous buck topology for efficient power conversion
• Adjustable output voltage capability within specified limits
• Automotive-grade thermal performance for high-temperature environments

Applications

• Automotive electronic systems
• Point-of-load DC-DC conversion
• General-purpose power management circuits

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as historical records indicate variations across production batches. Check current availability status as the part may be subject to discontinuation or lifecycle changes requiring immediate supply chain assessment.

Selection Notes

Select this component when a synchronous buck converter with wide input voltage tolerance is required. Ensure the design accommodates the 1.5A current limit and 260kHz switching frequency constraints. Verify that the SOIC-8 package fits the PCB layout requirements and that the thermal dissipation meets the 150°C junction temperature specification.

Part Context

This model belongs to the CS5141X series of 1.5A buck regulators from onsemi. The series includes variants operating at different frequencies such as 520kHz. The CS51412 specifically denotes the 260kHz version. It serves as a core power management integrated circuit within the broader PMIC portfolio designed for robust industrial and automotive use cases.

Replacement Considerations

NCV51411DR2G is documented as a parameter-equivalent substitute.
