CS5112YDWF24G

Overview

The CS5112YDWF24G is an AC-DC offline switching controller/regulator manufactured by onsemi. It integrates a 1.4 A switching regulator with a 5.0 V, 100 mA linear regulator that includes watchdog, RESET, and ENABLE functions. The device operates within a specified temperature range suitable for industrial applications.

Feature Summary

• Integrates a high-current switching regulator with a dedicated low-power linear regulator
• Includes built-in watchdog timer, reset generation, and enable control logic
• Designed for AC-DC offline power supply applications

Applications

• AC-DC offline power supplies
• Industrial control systems requiring integrated regulation and monitoring
• Power adapters with system management features

Procurement Notes

Verify the specific suffix YDWF24G against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the DWF24 package. Confirm RoHS compliance status through current manufacturer documentation before procurement.

Selection Notes

Select this component when an integrated solution combining primary side switching control with secondary-side auxiliary power and system monitoring is required. It simplifies design by reducing external component count for regulation and reset functions compared to discrete alternatives.

Part Context

This part belongs to onsemi's family of AC-DC offline switching controllers. It is distinct from general-purpose regulators due to its specialized integration of switching control with auxiliary linear regulation and digital monitoring features tailored for offline power conversion topologies.

Replacement Considerations

Check for NCV8141 or CS2001 as potential functional equivalents in similar application contexts. Verify pinout compatibility and electrical parameter alignment with original design requirements before substitution.
