CS51411ED8

Overview

The CS51411ED8 is a low voltage buck regulator IC manufactured by onsemi, designed for high-efficiency DC-DC conversion. It operates with an input voltage range of 4.5 V to 40 V and provides an adjustable output voltage from 1.27 V to 38 V. The device supports a continuous output current of 1.5 A and features selectable switching frequencies of 260 kHz or 520 kHz. It includes external bias or synchronization capabilities and is housed in an 8-SOIC package.

Feature Summary

Supports external bias or synchronization functionality
Adjustable output voltage configuration
Selectable switching frequency options

Applications

Industrial power supplies
Telecommunications equipment
Point-of-load regulation

Procurement Notes

Verify the specific suffix 'ED8' against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS compliance status as legacy variants may differ. Check for obsolescence notices or last-time buy notifications before finalizing procurement plans.

Selection Notes

Select this component when a synchronous or asynchronous buck converter with external control signals is required. Ensure the application demands an input voltage up to 40 V and requires precise frequency synchronization with other system clocks.

Part Context

This part belongs to the CS51411 family of low voltage buck regulators. It shares core specifications with variants like CS51411GD8 but differs in packaging or specific manufacturing revisions. It serves as a versatile solution for converting higher bus voltages to lower logic or analog supply levels.
