• AC-DC offline power supplies
• Switching regulator circuits
• Systems requiring integrated voltage regulation and reset monitoring

Procurement Notes

Verify the specific suffix 'YDWF24' against official onsemi documentation to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with required operating conditions and regulatory standards before procurement.

Selection Notes

Select this component for designs requiring an integrated offline switching controller with auxiliary linear regulation. Evaluate the 1.4 A switching current capability and 5.0 V LDO output against system load requirements. Confirm that the watchdog and reset features align with system safety and reliability needs.

Part Context

The CS5112 series belongs to ON Semiconductor's portfolio of AC-DC offline switching controllers. These devices combine primary side switching control with secondary side auxiliary power generation, simplifying power supply design by reducing external component count.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic equivalents may not match the integrated watchdog, reset, and enable feature set or the specific 1.4 A/5.0 V/100 mA configuration.
